The gorgeous life of rebirth

Chapter 20

But before she had time to open her mouth, Lu Lan, who was sitting next to her, suddenly grabbed her wrist tightly. She frowned in pain and subconsciously turned her head to look, but saw Lu Lan smiling calmly and saying to her: "Senior sister!" , The Qing is self-clearing, you have to argue for yourself, and wait until Huo Ting has finished speaking before you argue?!"

Lu Lan's voice was not low, and she quickly attracted the attention of the people around her. Everyone turned their attention to her, and she immediately felt a little embarrassed. Although she had already anticipated the unfavorable situation that would happen later, she knew that if she Standing up impatiently at this time will give people a sense of guilt, and there is Lu Lan sitting next to her, who is watching covetously. She is sure that as long as Lu Lan is there, it is impossible for her to refute, so now she can All she did was stand still, and she didn't believe that Huo Ting was so amazing.

And Huo Ting's words continued, "At the beginning, I measured the distance of the lawn that Cheng Yanshan rolled over. Everyone knows that the calculation formula of sliding friction is gravity multiplied by the coefficient of friction. After many studies, the lawn and the human body The friction coefficient is about this value." Huo Ting pointed to a number on the slide, "The next calculation is simple, assuming that Cheng Yanshan only weighs 40 kg, then the gravity multiplied by the friction coefficient is so much, And everyone also knows that the rolling friction is about one-sixtieth to one-fortieth of the sliding friction, so let's take the smallest value, which is one-sixtieth of the sliding friction, and then multiply it by the distance It is the work done by the friction force, so you might as well calculate it to see if it is the value I gave.”

After Huo Ting's voice fell, many people took out their mobile phones and counted, and then nodded affirmatively.

"According to the principle of energy conservation, Cheng Jiayao must have such a lot of strength to do it." He pointed to a value behind the formula, "But I checked many times, a normal adult It is impossible for a woman to have such a large thrust to allow another adult woman to overcome the friction force and do such a great work, not to mention that there is still a small slope between the Qingshizi road and the high ridge. Gong, that’s bigger than this number.”

As soon as his voice fell, the atmosphere at the scene was instantly dead silent. Although Huo Ting had a weird personality, his achievements in physics were obvious to all, and his words were also very authoritative. The following discussion, while more people looked at Cheng Yanshan with a deep look.

Cheng Yanshan's complexion can no longer be described as ugly, Huo Ting's proof is very telling, she didn't expect this guy to be so weird!And what he said was well-founded, and she couldn't even take the opportunity to find out his loopholes.

And Huo Ting's words are not over yet, "So to sum up, unless Cheng Jiayao has Kamepai Qigong, this matter is impossible to complete! However, there is another possibility."

The people below were laughing because Huo Ting, a serious person, could tell a joke, but they didn't expect him to say such a sentence suddenly, everyone cheered up instantly, and looked in his direction eagerly.

And Cheng Yanshan's heart, which was already so heavy that it couldn't sink any more, suddenly lifted up, and a pair of eyes looked at him with expectation and pleading, and only hoped that things would turn around.

"This may be that the person who was pushed down deliberately did work through the strength in his body, that is to say, he rolled himself from the lawn into a dry ditch."
