Metropolis: My IQ is 300

Chapter 46

The forty-fourth chapter is also called difficulty? (Seeking support, fourth more)

Physics is different from mathematics. Physics contains too many types. For example, as long as people stand here, force will be generated, movement, and friction will occur.

The universe will have a magnetic field.

The optics will move in the body.

Cells in the body also breathe.

Wait, these are all test sites that can be expanded.

Traditional physics are rigid topics. These topics are good for students because they are more formulaic.

But if the physics problem becomes not rigid.

Combined with reality, then the topic itself is very interesting.

One: A small ball with a mass of M=0.2 kg is placed on a vertical column, and the column height is h=5 meters. A bullet passes through the center of the sphere horizontally, the bullet mass m = kilogram, and the velocity v0 = 500 m/s. The ball falls on the ground at a distance of s=20 meters from the column. Ask where did the bullet fall on the ground? How much of the bullet’s kinetic energy is converted into heat?

2. Throw a rectangular object onto an ideal elastic wall. One side of the wooden block is parallel to the wall for the entire time, and its speed v is the same as that of the wall.

The normal line of is at angle a, and the friction coefficient of the wood block against the wall is. Find the relational expression between the reflection angle and the incident angle, and draw the function image of the relational expression.

The writing on the paper is very simple, with different languages ​​in different countries, this question is to combine the strength and other aspects of the data.

The mathematical function used at the end is a difficulty in itself.

The combination of cartography is already considered as a semi-combination with actual problems.

Chen Fan looked at the question, and finished the answer for one minute.

Simple calculations are really too easy for Chen Fan, without any challenges.

If this is a physical problem, then Chen Fan thinks his teammates are okay.

But looking down, it’s not quite right.

Chen Fan found that the problem was running away.

These thirty points are not so easy to take.

What we are now discussing and studying are two launch plans for a certain space research plan to launch a spacecraft out of the solar system. The first is to launch the spacecraft at a speed large enough to make it directly escape the solar system. The second option is to make the spacecraft approach an outer planet and rely on its help to change the direction of motion of the spacecraft to reach the speed required to escape the solar system. Assume that the spacecraft is only moving in the gravitational field of the sun or planet. So whether it moves in the gravitational field of the sun or the gravitational field of the planet, it depends on which field is stronger at that point.

All the text, the end, this is all the conditions given.

Seeing the moment, a student went crazy.

I’m going to fuck you, how about you playing Laozi?

Your uncle, what kind of earth are you okay with?

Why, can’t the gravity of the earth catch you anymore”

Or the food at home is not delicious, so what physics should I study?

Grandpa Hawking is also a pitfall. If you have any conjectures about the universe, how can you figure out the universe?

A bunch of trash can’t get out of the galaxy, what are you going to do? 》

Laozi is disgusting.

What am I writing?

What can I write now?

How much do you give me data?

However, there is nothing more than the basic symbol data.

Let’s look at the question again. Is this written by someone?

(1) Determine the minimum velocity v1 relative to the earth movement required to launch the spacecraft and its direction according to plan 1.

(2) It is assumed that the spacecraft has launched in the direction determined in (1), but has another velocity v2 relative to the earth. Find the speed when the spacecraft passes through the orbit of Mars, that is, the parallel and vertical components relative to this orbit. When the spacecraft passes through the orbit of Mars, Mars is not near this intersection.

Hehe, hehe, Laozi is going to kill the first person to go to the moon, and the first people to leave the earth.

Ah ah ah ah, sick of it, sick of it, the writing in the end is Shaya?

I don’t need to read the rest at all, because I’m about to vomit, it’s already very difficult to simply read this question and extract the answers you need.

Laozi won’t, can’t you skip it?

Go on to the third question.

“On one side of the straight track of a bicycle racing field, there is a slope with high outside and low inside, and the inclination angle is L. The length of the straight track is L, and the top

The height is h. As shown in the figure, the athlete starts at point A and the end point is A’. Athletes can choose to travel on a straight line AA’ or along a symmetrical broken line AMA’. If the speed of the bicycle at the start is v0, and the driving force when the athlete pedals is equal to the resistance, and the lateral friction between the wheel and the ground is sufficient to prevent the wheel from sliding, if you want to achieve better results , Which route should the athlete take? ”

This is great.

Hahaha, hahaha.

The boy reached out his hand and grabbed his face, trying his best not to cry. He really couldn’t cry.

be strong.

I think mom made pizza, and the turkey at home.

I want to go home, this is not an exam, you are murdering.

“That classmate, please don’t whisper and do the problem with speed.”

The best way to deal with genius is to make everyone stupid, including the genius yourself.

This is physics, mathematics, will help each other.

Physics does not deal with each other, because your research may be similar to mine.

Physics is a tycoon, and mathematics is only possible if you are engaged in stock trading.

Physics will always face the difficulties of people from all walks of life and crawl the Internet step by step.

Chen Fan raised his hand.

“This classmate, what is your problem?”

“It’s okay, hand in the paper.”

This…this.

“Classmate, what are you talking about, I’m not quite clear.”

“I said handing in the paper. In addition, there was an error in the second question. The universe, I think the magic group explanation I gave is already very clear. If a new theorem appears, then this kind of shaped environment should not appear. I refused to answer the question, so I turned in the paper.”

This… f*ck.

I forgot about it.

Big brother, if you come up with the theorem, you have to wait for us to digest it.

It’s obvious that you are like this, I’m an idiot.

And Chen Fan handed in and left, attracting the rest of the exam room.

“Teacher, I also think…”

“Shut up, you are not Chen Fan, answer the questions honestly for me.”

Damn, I want to complain, you treat our group of candidates differently.

ps: Please support, thank you all. .
