Chapter 238

"Chengnuo, let's go." After standing on the side and watching for a while, Muleng turned his head and opened his mouth to Cheng Nuo beside him.

"Why, don't you want to get involved?" Cheng Nuo did not intend to go.

Mu Leng frowned slightly, "aren't you afraid of heights? What's more, this challenge project is almost impossible to challenge a successful one. That necklace is there, just as a decoration, no one can take it away

Cheng Nuo tone is very serious, "ah Leng, you like that necklace, right?"

Just now, when the diamond necklace appeared in the eyes of all the people present, the look on Muleng's face was fully received by Cheng Nuo on the side.

Infatuation, love!

Obviously, in the face of that exquisite diamond necklace, even a girl like Mullin can't resist its charm.

Mu Leng gently nodded, but still quite rational, "yes, I like it, but..."

"No buts." Cheng Nuo took the opportunity to just hold Mu Leng's small hand and spoke in a firm tone, "ah Leng, believe me, we challenge, maybe we succeed?"

"As for the fear of heights or something, I believe I should probably probably not be as serious as when I was on a roller coaster."

"You Are you sure? " Mu Leng looks at Cheng Nuo suspiciously and adds, "the highest height of the roller coaster is only 42 meters, but the height of the jumping machine seems to be 110 meters. "

"Ah, ha ha! 110 meters! " Cheng Nuo subconsciously shrunk his neck and said, "ah Leng, I think the challenge is too difficult, or I'll give up! It's wise to know a man and leave. "

"Late." Mu Leng suddenly turns the corner of his mouth, pulls up Cheng Nuo's sleeve and pulls him to the registration position.

At the registration office of the challenge project, the crowd has dispersed a lot, but there are still dozens of people eating melons around here. At this time, a couple in their twenties had a dispute with the staff.

"Ah, are you playing tricks on us in this project? It's so difficult. How can you challenge success?" The girl in the couple took the lead in questioning.

"Yes, five batches have been changed. Even one person over 1L has not appeared, let alone 1.95l. You are pure hearted and let you fail in the challenge!" The boy also spoke.

The staff waved their hands and repeatedly explained, "madam, sir, you have misunderstood that our amusement park is not going to let you step on your left foot and your right foot into the sky. There must be a chance of success. However, we can't make the challenge project too simple, otherwise everyone can challenge successfully. Then we don't have the financial resources to give each of you a necklace worth more than 80000, don't we? "

"So, this project is difficult, but it is not very difficult to achieve. The reason why everyone in front of you successfully challenged is that you did not master the correct method. Challenge a few more times and you should be able to find a way. Anyway, we will hold this activity for a total of seven days, so don't worry. You can't make it more than once

A ticket is eligible for only one challenge, which means that if someone wants to challenge for a second time, they must buy another ticket. In this way, ticket sales will undoubtedly increase.

After seven days of accumulation, the new and unwilling customers can earn at least hundreds of thousands of tickets.

It has to be said that the marketing plan of the amusement park is very beautiful.

Unfortunately

Couple two people also some believed the staff's lies, the head is dizzy, "you said is true?"

"Of course, when we sell, can we tell lies? This challenge project, is absolutely someone can challenge the success! This project is very simple The staff laughed and wanted to find someone to corroborate his remarks. When their eyes turned, they suddenly caught a glimpse of Cheng Nuo, who was standing opposite him. Laughing, he casually asked, "little brother, do you think I'm right?"

Cheng Nuo was stunned for two or three seconds, nodded heavily and thumbed up, "that's right. This project is really simple. If my girlfriend didn't want the necklace, I wouldn't have bothered to participate in such a simple project. I suggest you make the challenge a little harder next time. "

"Ha ha..." At a glance, the staff gave a sneer.

Should we say that you are a newborn calf who doesn't beat the tiger, or do you know nothing about the difficulty of this project.

Simple?! That's just a lie. If it were simple, they would not have moved out of the project.

However, Cheng Nuo's words have not stopped. "You should have held this activity today. You said, if your prize is taken away on the first day, it should be ok? If it matters, I'll give up the challenge and not give you any trouble. "

"Er..." The staff were black.

Listening to Cheng Nuo's tone, it seems that he is fully confident that he can challenge success. In that case, it seems to give the amusement park enough face.

But the key is Where did you get the courage to say that?! Did Liang Jingru give it?This is The challenge is impossible!

Although my heart mother sells approval, the staff's face is still polite, "no, no, as long as you can challenge successfully, you can take this string of items on the spot, and you don't need to pay any appraisal fees and other fees. It's completely free."

"Well, I'll be relieved." Cheng Nuo most afraid to give others trouble, see the staff said so, instantly put at ease. He took out the tickets for himself and Mullin and handed them to the staff, "well, we sign up."

"Good. Please register The staff nodded readily and agreed, "you two should be able to go on the next batch."

By this time, the sixth group of men and women in eight groups had risen to the highest altitude of 110 meters.

With a shrill cry, the water scattered all over the sky. It was like a drizzle in the sky.

Ten seconds later, all eight groups of personnel landed safely, and two staff members immediately rushed forward to measure the water volume in the sink above their heads.

The situation is a little better this time, and the group with the largest amount of residual water reaches 1.25l.

However, there is still a big gap between 1.95l and 1.95l.

"Go up, everybody. I'll put the device on for you

The seventh batch of 18 people sat on the seats of the jumping machine, including Cheng Nuo and Mu Leng.

It was the registration staff who put on equipment for the two people and poured 2L of water into the sink.

Cheng Nuo tried to move his neck a little, and he could feel the water sloshing back and forth in the sink above his head. Cheng Nuo stopped immediately.

Fortunately, the sink is not full. Otherwise, the amount of water will be 0.05l.

"Ah Leng, remember what I said. Later, you can do what I ask you to do, you know?" Cheng Nuo straightens his neck and says he dare not move.

Muran also Cheng Nuo's state is similar, white palm grasps the armrest, straightens his chest and looks up, "Cheng Nuo, do you really have confidence?"

"No problem, believe me." Cheng Nuo's tone is firm.

Mu Leng chuckled, "well, I'll listen to you."

While they were talking, the machine began to rise at the same speed.

10 meters, 30 meters, 50 meters

…………

110 meters, equivalent to the height of thirty or forty stories.

Looking down into the distance, you can get a glimpse of the whole amusement park. There is a sense of boldness and boldness to be able to stand at the top of the mountain. A panoramic view of all the scenery.

Only 16 people, including Cheng Nuo Muleng, were not in the mood to enjoy such a beautiful scenery at this time.

Cheng Nuo, who has acrophobia, is even more closed his eyes, and does not dare to look down at him at all. Otherwise, the strong vertigo will definitely make him confused.

"Chengnuo, we're at the top." Muran takes Cheng Nuo's hand and whispers in Cheng Nuo's ear.

"Good." Cheng Nuo, a little pale in his face, nodded gently, "ah Leng, I'll call three two one for a while, and we'll do as I say. Do you know?"

Muran nodded. "OK, I'll listen to you."

Cheng Nuo's face became extremely serious, counting the numbers in his mind.

When the machine reaches the highest point, it will stop at the highest place for 5 seconds. This time is a fixed value, not a variable.

Five seconds later, the machine will fall at the rate of free fall.

The water in the tank will lose a certain amount due to the inertia. Therefore, if you want to control the remaining water above 1.95l, you must find a way to offset the inertia.

How to offset it? Cheng Nuo came up with a way that is still feasible at present.

Cheng Nuo has seen it with his power before. The acceleration of gravity at the location where the jumper is located is 9.857 meters square second. The actual water volume in the water tank is 2.005l and the weight is 2.004 kg. The weight of the whole device is 3.218 kg. Of course, since it is manual operation, there is an error of 5 ml, which is inevitable.

What's more, only 5ml of water is difficult to make a decisive impact on the success of the challenge.

When the body falls freely, the acceleration of gravity is 9.857 m quadratic second, and the water in the water tank will have a short "stagnation" due to inertia. At this time, this inertia can be eliminated by giving it a short upward acceleration of 9.857 m quadratic second.

However, it is too difficult to grasp the opportunity. Moreover, the upward acceleration given must be 9.857 meters square second, so as to minimize the water loss in the air.

For ordinary people, this is almost impossible. After all, it is too demanding for time and strength. Amusement park also thought of this point, so it is so unscrupulous to let people challenge.

However, ordinary people can not make it come true. But for Cheng Nuo, it's just a basic operation. It's just because Mullen and he are challenging together, so it's a little bit difficult.5！ 4！ 3！……

Cheng Nuo's eyes are like a stopwatch, the number is constantly beating.

"Three, two,..." Cheng Nuo clenched Muleng's hand and opened his mouth word by word.

0.95！ 0.85！ 0.52 seconds

"One!"

In an instant, the fixed system of the jumper was released. Due to the effect of gravity, the jumping machine starts to move at the speed of zero initial speed and acceleration of G.

At the same time, at the moment of Cheng Nuo's voice falling, Cheng Nuo and Mu Leng grab the armrest with both hands, and their necks suddenly go up.

F=ma。 The value of M has been determined to be 3.218 kg. The value of a is equal to the value of G, that is, 9.857 m quadratic second. Then f, which is the value of force required by two people, is calculated by the formula to be 31.719826 n.

They need 31.719826 cattle in total, and the best plan is that they use 15.86 cattle of force respectively. However, Mullin has no ability of Cheng Nuo, so he can't control his strength. Therefore, Cheng Nuo should first know the force used by Mullen.

Because the neck can not move, Cheng Nuo can only squint at the various values of Muleng.

"Height Force 15.287 n! "

287 cattle, not bad, much better than the predicted value. In this case, if the challenge is successful, there should be no big accident.

With this in mind, Cheng Nuo controls his body and uses 16.432 cow's force.

From a bird's-eye view, at the moment when the plane began to descend, a lot of water in the other seven groups of tanks on the plane was scattered due to inertia. The excess of 0.05l is positive.

On the other hand, the 2l volume of water in Chengnuo's and mulen's flumes did not show the inertial effect of other groups, but the water slightly swayed in the tank. Because the water didn't fill the whole sink, only a few drops were spilled out. A few drops of water, just a few milliliters, and 50 milliliters must still be very safe to lose water.

Speed up, speed up!

The free fall speed of the jumper is increasing at a rate of nearly 10 meters per second. Up to 38.58 meters square second.

When it is about 20 or 30 meters away from the ground, the speed drops slowly and lands safely under the action of deceleration equipment.

Two staff members quickly come forward, holding a graduated tank, in turn to measure the remaining water of these groups of people.

The first group, the remaining 0.58l, the second group, the remaining 0.25L, the third group, the remaining 0.00l

The result is still bleak as usual. The two staff members have long anticipated this situation, both of them continue to verify their normal mentality.

In the sixth group, there are Mullen and Cheng Nuo.

That staff member to Cheng Nuo ha ha, "little brother, how, feel oneself challenge success?"

Cheng Nuo also ha ha a smile, "I feel also OK."

The staff are also amused by Cheng Nuo's confidence. You guy, you don't cry when you don't see the coffin!

"Well, I'll see how much more you have left." The staff sneered and reached out to remove the sink fixed on the two people's heads.

Heavy! This is the first feeling of the staff.

It's the first time he's ever felt such a heavy sink. Looking down, sure enough, there is quite a lot of water left. It's more than he's verified before, and it's a lot more.

So much, how can it be?!

With regard to the amount of water, if it was not for seeing it with their own eyes, the staff even suspected that Cheng Nuo and Mu Leng were not on the jumping machine at all.

With uneasy mood, the staff put the water in the sink into the scale tank.

0.25L，0.5L，0.75L……

A scale, slowly submerged by water. When the water volume reaches 1L, it is obvious that there is still a lot of water left in the tank.

The crowd watching the excitement saw this situation, and they all gave a cry of surprise.

Is Can they challenge success?

Scales, rising one by one. 1.25L，1.5L，1.75L……

Finally, the amount of water was fixed at 1.98l. In other words, after a trip back from the jumping machine, the water loss was only 20 ml.

The whole process was in uproar. This is simply an unimaginable number.

Cheng Nuo stretched out his hand and showed a harmless smile in front of the staff, "in this way, I should be considered successful in the challenge."

"Then, give me the necklace."
