Wang Duoyu wiped the blood splattered on his face. He saw that although the person who fell on the ground was lying on his stomach, his head was turned around, and his blood-stained eyes were facing him.

Only then did he realize that the person who fell to the ground was one of the female participants who had disappeared before.

"ah!"

Wang Duoyu was so frightened that he couldn't help but take a few steps back. He didn't stop until a pair of strong hands pressed his shoulders.

He looked back and found that the person supporting him was Wang Guoqiang, and he felt a little relieved.

Mo Shouchen stood relatively far back, so he was hardly splashed with blood. He raised his head and glanced at the ceiling. There was nothing on it, and there was no way he could hide anyone.

And even if a person fell from the ceiling, it would be impossible for him to fall so badly from such a small height, so this must be the work of the examiner.

Sure enough, not long after the person fell, the examiner walked off the stage with a blank expression on his face.

He walked to the body, and then used chalk to draw a long straight line on the ground two or three meters away from the body.

After finishing the painting, he stood next to the body as if nothing had happened and said: "Now I will talk about the questions for the physics exam."

"It is known that the height of the building is 20 meters. This person fell 3.5 meters away from the building. He did not hit any objects during the fall. Now you need to verify, did this person jump off by himself or was he pushed down?"

"The exam lasts for one hour. If you answer incorrectly, you will be eliminated."

After reading the topic, the examiner walked back to the podium with his hands behind his back, then picked up the book and read it carefully.

The straight line he just drew on the ground should represent the edge of the building. He fell from a 20-meter-high building. No wonder he fell so hard.

Although the corpse looked very scary, in order to complete the exam, except for "Jue Huang", the remaining 11 participants still gathered around the corpse and began to think about the examiner's question.

At this time Wang Guoqiang said: "I watched a movie some time ago with a similar plot. I remember that there seemed to be some kind of experiment in the movie."

"What it means is that if a person jumped from a high altitude by himself, it would be a free fall, and the landing point should be directly below. I see that the body is a certain distance from the building. It should have been pushed down, right?"

"Sig experiment." Ren Changqiu said.

"Yes, it seems to be called the Sig experiment!" Wang Guoguo nodded vigorously.

Ren Changqiu touched his chin and said: "Everyone should have seen the movie you mentioned, but as an engineer, when I watched this movie, I found that the plot was not rigorous enough."

"The Seager experiment can indeed prove that when an object falls by itself, the landing point should be directly below the falling position, but they ignored another factor."

"Because the human body is top-heavy, it will rotate when it falls. When the rotation angular velocity vector of a rotating object does not coincide with the object's flight speed vector."

"A transverse force will be generated in the direction perpendicular to the plane composed of the rotation angular velocity vector and the translation velocity vector. Under the action of this transverse force, the flight trajectory of the object will deviate. In physics, this phenomenon is called Magnetism

Nuss effect.”

After Ren Changqiu finished speaking, he found that everyone looked at him with expressions that looked like he had been constipated for days.

Mo Shouchen smiled bitterly and said, "Can you make it simpler?"

"Oh, sorry!"

Ren Changqiu touched his nose awkwardly: "To put it simply, if a person's body rotates when jumping off a building, the landing point is not necessarily directly below the falling position, and may shift."

Mo Shouchen nodded as if he understood, and then said: "Then can you figure out whether she jumped down by herself or was pushed down by someone?"

"I can try." Ren Changqiu replied.

Mo Shouchen patted Ren Changqiu's shoulder and said, "Okay, then it's up to you!"

Now there is no other way but to place our hopes on Ren Changqiu's professional knowledge.

Ren Changqiu took out paper and pen, and then drew and wrote on them.

At first, Mo Shouchen stood by and took a look, wanting to help give some ideas or something, but when he found that he couldn't understand it at all, he simply gave up.

After spending more than half an hour and writing five pages, Ren Changqiu breathed a long sigh of relief, and then said: "I calculated it. Based on the position of the body, there is a 90% probability that he jumped down by himself.

"

Mo Shouchen frowned and asked, "Can't you be 100% sure?"

Ren Changqiu shook his head helplessly: "I have done the math three times, but if a person falls from a twenty-meter-high building, there will be many variables."

"Just like there are no two identical leaves in the world, even if the same object falls, its position will be different every time."

Mo Shouchen looked at the densely written pages in Ren Changqiu's hand, pondered for a moment, and then looked up at Chen Ying.

After seeing his eyes, Chen Ying nodded slightly.

They had discussed countermeasures when they were in the toilet just now.

Once he made a mistake in the subsequent exam, Chen Ying immediately used the 20 extra points in his hand to exchange for "getting help from the examiner for fifteen minutes."

Although I know that even if I redeem this, I can't change the outcome of being eliminated, but I can at least buy some time.

If it really doesn't work, the worst possible outcome is that you'll have to fight with the examiner, and you definitely can't just sit back and wait for death.

However, this strategy also has a fatal flaw, that is, if Chen Ying changes his mind temporarily and directly exchanges for "passing the exam in class" to avoid being eliminated, the situation will be somewhat passive.

To be honest, based on what Chen Ying has done in the past, Mo Shouchen has little confidence in him.

But now he is the only one with 20 extra points, so we can only hope that he will not mess with everyone at the critical moment.

After exchanging glances with Chen Ying, Mo Shouchen asked Ren Changqiu to find the examiner to reveal the answers. By this time, everyone's hearts were already in their throats.

After listening to Ren Changqiu's answer, the examiner's face was expressionless and he couldn't tell whether it was right or wrong.
