Chapter 238 (2/2)

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.”
