Chapter 135 Two Iron Balls Landed Simultaneously
"Okay, listen carefully. There is a large ball weighing ten catties and a small ball weighing five catties. They are dropped from a tall building at the same time. Ask what will happen. A answers that the big ball hits the ground first; B answers that the small ball hits the ground first; C answers Both balls hit the ground at the same time."

Huang Meng asked with a smile.

After asking, there was a burst of laughter.

Many people immediately said: "Of course the big ball hits the ground first, does that need to be said?"

"That's right! The heavy ones will fall to the ground first!"

"What kind of problem is this? I knew it when I was one year old!"

Li Tai also wanted to say that the big ball landed first.

But he was played by Huang Meng once.

A little alert.

This question seems to have a simple answer, but in fact... it may be a trap.

How could Huang Meng ask such an easy question.

But the problem is that simple.

This is a question of common sense.

"Could it be that the ball hit the ground first?" Li Tai thought in reverse.

Huang Meng cast his gaze over.

Li Tai said in a straight voice: "I choose A."

In the end, he chose to be like everyone else.

Huang Meng looked at Wang Xiaotong again, and Wang Xiaotong was also lost in thought.

He didn't think Huang Meng would ask random questions.

This question is definitely related to mathematics.

Should not be simple.

Huang Meng said: "Who else has a different opinion?"

Huang Meng looked at Cheng Chumo and the others.

Cheng Chumo said: "Little Ball..."

Everyone said it was a big ball, so he wanted to support Huang Meng's talk about a small ball, but was stopped by Niu Hao.

"Brother Tieniu, choose C!"

"Hmm! What did you say?" Cheng Chengmo asked in a low voice.

How could it be possible for two balls to land together.

Even if you are wrong, you should choose B.

Niu Haochong winked and said: "I heard Brother Dameng tell Xiaomeng once when he was teaching sister Xiaomeng, it seemed that two balls landed together."

"Are you sure!" Cheng Chumo's eyes lit up, and he regained his spirit all of a sudden.

Now Niu Hao scratched the back of his head and said, "This, it seems to be..."

Cheng Chumo slapped him, gave him a blank look, and said, "I choose C, and the two iron balls will fall to the ground at the same time!"

"Hahaha……"

Cheng Chumo's answer drew a burst of laughter.

"Cheng Dabiao, I just thought you were stupid before, but now I think you are really stupid!"

"That's right, how could it be that two iron balls hit the ground at the same time, of course the heavier one hit the ground first..."

Li Tai looked at Huang Meng and said, "Let's reveal the answer!"

Only then did everyone turn their eyes to Huang Meng.

Huang Meng said: "What Cheng Chumo said is correct, the answer is C, the two iron balls landed at the same time!"

"Hahaha, I knew what I said was right, you bunch of weak scum..." Cheng Chumo grabbed Niu Hao and winked at Huang Meng, as if to say, he is a brother, he is strong enough.

"How is this possible! Don't deceive us."

"Exactly! Do you really think we are fools?"

Wang Xiaotong couldn't figure it out either, so he came over and said, "Dalang, why is this?"

Huang Meng said: "Find two stones of the same material, we will order people to climb to the top of the building, let go of the stones at the same time, and do an experiment to find out."

Wang Xiao said: "That's right, do an experiment to know the truth."

Cheng Chumo said: "I'll come, I'll come, I'm the best at going to the room!"

So Cheng Chumo climbed up to the highest roof of the Mathematical Academy.

Then everyone found two stones that were about twice as large and sent them up.

Cheng Chumo held a piece in one hand.

Huang Meng said: "Chu Mo, let go at the same time, don't make one slow and the other fast!"

"Don't worry about Dameng, I won't cheat." Cheng Chumo released his left and right hands at the same time.

Two stones of different weights fell from above in an instant.

Everyone is watching.

His eyes moved as the stone fell.

This process is very short.

Soon two stones fell to the ground.

Then everything became quiet.

"Did they fall together?"

"It seems to be... almost!"

"I didn't see it clearly, anyway, it fell to the ground with a bang!"

Wang Xiaotong said: "It landed almost at the same time, but there is still a slight difference, but it is too difficult for the naked eye to detect."

"Because this height is not enough, if there is a ten-story tower high and iron balls of the same material are used, it will be more intuitive and the gap will be smaller, basically the same." Huang Meng explained.

Wang Xiaotong nodded in understanding.

It is impossible for Huang Meng to lie to him.

Speaking of this experiment, many prerequisites are required.

So he asked, "What's the reason?"

This experiment is too abnormal.

It's against common sense.

Huang Meng said with a smile: "Simple, because the earth has a gravitational force, and it has the same attraction for things of the same material.

The speed at which an object falls has little to do with the initial velocity, and the density of the material has little to do with the weight of the object itself. "

"So that's the reason why you have to use iron balls of the same material and put them down at the same time." Wang Xiaotong figured it out, and became more interested.

So he said to the students: "You can do this experiment repeatedly when you go back, and try to put the iron ball from a high place. This is your homework for today."

"Yes, sir!"

Everyone bowed their hands in worship.

Huang Meng looked at Li Tai: "How about defending His Royal Highness!"

"I'll talk when I finish the experiment!" Li Tai snorted coldly, turned and left.

"Hahaha, you are the best in Dameng. Now you have given these guys a good blow. Let's see if they dare to look down on us in the future." Cheng Chumo said proudly, as if he had won a battle.

Huang Meng said: "Okay, let's go home!"

"Okay! Go home."

That's the end of a day's schoolwork.

Everyone is like a released cow, finally able to have fun.

After leaving the Imperial College, Huang Meng told Yuchi Baolin about the soap.

Yuchi Baolin was overjoyed, and said that he would notify his family, call the place as soon as possible, and set up the soap shop, there would be no delay.

When he got home, Gao Deyi was waiting for him in the shop hall.

"Xiao Langjun is finally back, so let our family wait. I heard that Xiao Langjun was put on leave by his master when he was young." Gao De laughed.

Huang Meng said: "Why do you bother Eunuch Gao to come here again? Could it be that His Majesty has heard some embarrassing things about me again, and you are bothering the old man to be worried and distracted?"

Kong Yingda is going to file a complaint.

Gao De said: "Your Majesty sent me to ask Mr. Hou Xiaolang. I heard that Mr. Hou has just recovered from a serious illness and is not in good spirits, so let me assist Mr. Hou to add those punctuation marks."

"Ahem, punctuation marks!" Huang Meng knew that Kong Yingda must have really gone to find Li Er.

This old man is very anxious.

As soon as I left with my front foot, I went to Li Er's place with my back foot.

And let Li Erlai urge him to get out the punctuation marks.

So he said with a smile: "Eunuch Gao, for His Majesty's affairs, Cao Min should do his best, but this matter is too important to be sloppy. I will do my best. Please go back and tell Your Majesty, Eunuch Gao, so that he can rest assured."

"Okay! Now that Mr. Xiaolang knows what's in his mind, I'll go back." Gao De didn't talk nonsense, he just came to deliver an order to urge Huang Meng.

He can't interfere with anything else.
