City Survival: The Program Group Is Going Crazy!

"This flower pot was thrown from A10 household!" Lin Beifan said.

"How did you find out?" Noda Hiroshi asked immediately.

Lin Beifan shook his head: "I didn't see it, I calculated it!"

"Calculate... Calculated?"

"How?"

Everyone was dumbfounded again.

"It's easy!"

Lin Beifan took out a notebook and paper from the backpack behind Bai Rongrong, and explained while drawing: "Look, everyone, according to Brother Hao's analysis and judgment just now, this flower pot can only be thrown from the residents on the sixth floor and above! Then, he There are only 5 possibilities for the falling parabolic trajectory, which are as follows..."

"The height of each floor is 3.5 meters, and the height of the windows is 1.2 meters. Then, if the vase is dropped from the 6th floor, then its vertical height is 18.7 meters; if it is dropped from the 7th floor, its vertical height is 22.2 meters. ..."

"According to the above information, combined with the calculation formula of gravitational acceleration h=1/2g(t^2), we can clearly calculate the time it takes for the flowerpot to fall from each floor. In this way, it is the horizontal movement of the vase

"The distance between the vase and the tall building next to it is a bit far, about 10.5 meters. Based on the time obtained above, we can calculate the speed V of the flowerpot in the horizontal direction..."

"It can be seen that the lower the floor, the faster the horizontal movement speed of this flower pot! Therefore, the greater the force required to act on the 363 flower pot! The weight of this flower pot is about 5 kg, according to the kinetic energy equation E=m(v^2), you can calculate how much work is acting on the level of this flowerpot..."

"The arm length of an adult is about 0.8 meters, but if you want to push the flowerpot out, the movement distance can only reach 0.6 meters at most! Assuming that this force is always constant, according to the work equation W=FS, we can get The force exerted on this flower pot has 5 values..."

"Among them, the lower the floor, the greater the force used! However, look at these values, among them, the 6th, 7th, and 8th floors, the value of this force has far exceeded the strength of ordinary adult men! Unless it is Only people who have been exercising for a long time and have achieved great results can use this force! Therefore, the flower pots are most likely to be thrown from the 9th and 10th floors......

"Brother Hao has analyzed it just now, A9, B9, and B10 have been ruled out, so only...A10 is left! He has the biggest suspicion!"

Lin Beifan raised his head: "Do you understand?"

But I saw everyone looking at him in a daze, and then looked at each other without saying a word.

Even in the live broadcast room, no one swiped the screen anymore, and they were all in a daze.

Only Noda Hiroshi thought about it.

One of the audience smiled awkwardly and said, "Little prodigy, can you say it again? I didn't understand it just now!"

"Yes, say it again!"

Lin Beifan said helplessly: "Okay then, I'll say it again!"

Therefore, Lin Beifan once again used physics thinking to explain the principle to everyone.

This time, everyone listened very carefully and finally understood.

"I'll go! So it was calculated like this, it's an eye-opener!"

"I finally understood it this time. I was completely using the knowledge of physics and sports. I was stunned! How can physics knowledge be used like this? It feels like I have passed three years of high school for nothing!"

"It should be said that crime-solving dramas can still play like this, directly targeting the murderer, it's awesome!"

"No wonder it's the best detective in the world, little mortal!"

"Little prodigy, I am convinced, completely convinced!"

"Little child prodigy, always be a god!"

We deeply admire.

He really calculated it, using physics knowledge to calculate it, it's amazing!

It doesn't matter if people don't admire it, let's bow down!

The five-body cast of admiration!

At this time, a person came out and left a message in the live broadcast room: "Let me ask weakly: what did the little prodigy just say, why did I still not understand it? (aeab)"

"Upstairs, did you not go to high school?"

"I did, but I..."

"That means you haven't done it properly, hurry up and go back and repair it again and you'll understand!"

"I don't even want to say a word to you, a scumbag!"

At this time, Noda Hao said calmly: "Little prodigy, your method of solving the case really shines in front of my eyes! However, there are still many restrictive conditions in it, mainly because of the data problem. Your method of obtaining data is too crude. If the data is wrong, there will be a big error, which will affect the final analysis result! A slight mistake is a thousand miles away!"

"One more thing, how can you conclude that this flower pot was thrown out horizontally? He can be thrown up or down! If it wasn't thrown out horizontally, your inference is all wrong!"

After listening to Noda Hiroshi's words, Yinjia once again fell into deep thought.

"Brother Hao is right, there is a big problem with this calculation method!"

"This is reality, and there will be big errors!"

"Unless you get the most accurate data, it really won't work!"

"Missing a tiny bit, wronging a thousand miles!"

"There is also a problem with the movement of the flowerpot. It doesn't have to be thrown horizontally!"

Lin Beifan chuckled: "I've considered this issue a long time ago! Just now, I've gone through all the data, calculated their deviations, and finally drawn a range! This range compares Big, but, the range includes the A10 all the way!"

"Huh? When did you calculate it? Why didn't I see it?" Noda Hiroshi asked.

"Just now, I have calculated it with my head, it's not a problem!" Lin Beifan waved his hand.

At this time, Yinjia remembered that Xiang also possessed terrifying mental arithmetic ability.

"As for the throwing method of the flower pot, I can basically be sure that it was thrown horizontally, or pushed out horizontally! Because this flower pot weighs 5 kilograms including the soil inside! With such a weight, you Do you know how heavy it is? It is very difficult for an adult to throw it up! Even if it can be thrown up, the height is not high, and it is still within my calculation range! Therefore, I am 90% sure that the flowerpot is It fell from A10!"

Everyone nodded, basically agreeing with his statement.

Then, Lin Beifan repeatedly pointed out several doubts.

"Look at the bottom of this flower pot, there are obvious scratches, and the direction of the scratches is obviously consistent, it looks very fresh! It may have been placed on the window sill, and was pushed down! Because the flower pot is too heavy, so With such scratches, there should be some traces on the window sill upstairs, we can use this to confirm each other!"

"And here...you see, what is this?"

"Isn't this just the soil in the flower pot? Is there something strange about it?"

"No, this soil is different. It is cat litter, which is used for cats to shovel excrement! Most people will not touch this thing, which means that this family should be a cat owner. They have cats.
