This Is Difficult? (Seeking Support)
Physics was different from mathematics. Physics encompassed too many types. For example, as long as a person stood there, a force would be generated. There would be friction when moving.
The universe had a magnetic field.
Optics could be used in body movements.
The cells in his body would also breathe.
Wait, these were all test points that could be expanded.
On the other hand, traditional physics questions were rigid. These questions were good for students because they were more formulated.
However, if the physics questions became not rigid…
Combined with reality, the question itself was very interesting.
One: A small ball with a mass of M=0.2 kg is placed on a vertical column with a height of h=5 meters. A bullet passes horizontally through the center of the sphere. The mass of the bullet is m=0.01 kg, and the speed is v0=500 m/s. The ball landed on the ground 20 meters away from the pillar. Where did the bullet land? How much of the bullet's kinetic energy was 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 the wall.
The normal line of the wood block forms an angle a, and the friction coefficient of the wood block against the wall is. Find the relationship between the reflection angle and the incident angle, and draw the functional graph of the relationship.
The writing on the paper was very simple. It was written in different languages from different countries. This question was a combination of strength and data from another aspect.
The mathematical function used at the end was a difficult point in itself.
The combination of the drawings was already considered to be a combination of the actual problem.
Chen Fan looked at the questions and finished writing the answers after one minute.
Simple calculations were too easy for Chen Fan.
If this was a difficult physics problem, then Chen Fan felt that his teammates were okay.
But when he looked down, something was wrong.
Chen Fan found that the questions were flying.
These 30 points were not so easy to obtain.
They were currently discussing and researching a space research plan. There were two launch plans for a spacecraft to be launched outside the solar system. The first method was to launch the spacecraft at a high enough speed, allowing it to escape the solar system. The second option was to get the spacecraft close to an outer planet and rely on its help to change the direction of the spacecraft to achieve the speed needed to escape the solar system. Assuming that the spacecraft was only moving in the gravitational field of the sun or planet. Whether it was moving in the gravitational field of the sun or the gravitational field of the planet depended on which field was stronger.
All the words, end. This was all the conditions given.
The moment he saw it, a student went crazy.
F * ck you, are you playing with me?
F * ck you, why did you come out of Earth?
Why, can't gravity catch you?"
Or was it because the food at home was not delicious and he had nothing better to do than study physics?
Grandpa Hawking was also a scammer. If you had come up with a conjecture about the universe for no reason, what could you do even if you left the universe?
A bunch of trash who can't even leave the Milky Way, what are they doing?》
I'm so disgusted.
What should I write?
What can I write now?
At least give me some data.
However, other than the basic symbolic data, there was nothing else.
Looking at the question again, was this written by a human?
(1) According to the first plan, determine the minimum speed v1 and direction of the spacecraft relative to the Earth.
(2) Assuming that the spacecraft has been launched in the direction determined in (1), but with another velocity v2 relative to Earth. Find the speed of the spacecraft passing through Mars 'orbit, which is the parallel and vertical components relative to this orbit. When the spacecraft passed through Mars 'orbit, Mars was not near this intersection.
Hehe, hehe, I want to kill the first person to go to the moon and the first batch of people to leave Earth.
Ahhhh, so annoying, so annoying, what exactly is written?
There was no need to look at the rest because he was about to vomit. Just reading this question and extracting the required answer was already very difficult.
If I don't know how to do it, can't I skip it?
Moving on to the third question.
"On one side of the straight running track of a certain bicycle competition ground, there is an inclined plane with a high outside and a low inside. The length of the straight running track is L, and the upper end of the inclined plane is
The height is h. As shown in the picture, the athlete starts from point A and ends at point A. Athletes could choose to travel in a straight line AA', or along a symmetrical line AMA '. If the starting speed of the bicycle was v0, and the driving force of the athlete was equal to the resistance, and the lateral friction between the wheel and the ground was enough to prevent the wheel from slipping, which route should the athlete use to achieve better results?”
This was great.
Hahaha, hahaha.
The boy reached out and scratched his face, trying his best not to cry. He really couldn't cry.
Be strong.
I miss Mom's pizza and the turkey at home.
I want to go home. This isn't a test. You're murdering me.
"That student, please don't whisper to each other and do the questions quickly.”
The best way to deal with geniuses was to make everyone stupid, including the genius himself.
This was physics and mathematics. They would help each other.
Physics doesn't work together because your research might be similar to mine.
Physics produced tycoons, and mathematics could only be done by investing in stocks.
Physics would always face difficulties from various people and climb up the internet step by step.
Chen Fan raised his hand.
"Student, do you have any questions?”
"It's fine. Hand in your paper."
This…this…
"Classmate, what did you say? I'm not quite sure.”
" I said to hand in the paper. Also, there was a mistake in the second question. Universe. I think the explanation I gave for the demon horde is very clear. If a new theorem appears, then this kind of environment shouldn't appear. I refuse to answer this question, so I'll hand in the paper.”
This…F * ck.
He had forgotten about this matter.
Boss, even if you have a theorem, you have to wait for us to digest it.
You look like an idiot.
Chen Fan turned in his paper and left, attracting the attention of the rest of the students.
" Teacher, I think so too…"
"Shut up, you're not Chen Fan. Answer the questions honestly.”
F * ck, I want to complain. You guys treat us examinees differently.
