Super Xueba: Start With A Low Control Score!

Chapter 14 Don’t hand in homework, just sleep in class!

The question is too simple?

No difficulty at all?

Do you want to try again?

f*ck!

Is this the human word?

Although the lethality is not great, it is extremely insulting.

One of the children’s shoes around is counted as one, and all of them feel hot on their faces and feel ashamed in their hearts.

after all……

They can’t do it all!

The same is a student.

This gap cannot be said to be insignificant.

School tyrants like Su Yu, Zhang Hao, and Tang Tiantian wanted to dig a hole right away.

They also suspected jealousy of Jiang Nan before.

Now I finally understand.

They didn’t put themselves in sight at all.

compare to.

Are you still a master?

The five scum of war is almost the same.

Even an elite like Qin Yumo was willing to bow down to Jiang Nan and was completely convinced.

The Fatty Wang next to him, looked at Jiang Nan with a grievance, and said silently in his heart, “I once said that I wanted to go together, but in the end I was really good, but brother, you flew?”

the other side.

Xie Hongwei, the physics teacher on the podium, was also deeply stimulated by Jiang Nan’s words.

Nothing to say.

Wipe the question on the blackboard.

“Da da da da” quickly wrote.

It took a long time.

Only one question came out fresh.

“An artificial satellite with a mass of m moves in a circular motion at an altitude of 800km above the ground, and at some point it collides head-on with a space debris with a mass of mi=m/9.”

“The collision time is extremely short, and then the two combine to form an object and move in an ellipse. The semi-major axis of the elliptical orbit is 7500km, and its orbit and the satellite’s orbit are in the same plane.”

“It is known that when an object m makes an elliptical motion around a blue star, its total energy is the sum of kinetic energy and gravitational potential energy.”

“G is the gravitational constant.”

“M is the quality of Bluestar.”

“A is the semi-major axis of the elliptical orbit…”

“…”

“(1) Try to demonstrate quantitatively, after the collision, will the combined object of the two fall on the blue star?”

“(2) If this event occurred in the sky above the north level (in the direction of the line between the center of the earth and the north pole), what is the latitude where the combined object and the blue star collided after the collision?”

“…”

Different from the previous multiple-choice questions.

this time……

Xie Hongwei presented a very complicated problem.

wrong!

Very complicated and inaccurate.

It should be said to be very hellish complex.

And this question came out.

“Fuck, the teacher must be invincible!”

“Densely and half the blackboards, it’s too much to look at!”

“Satellite? Space debris? You can get a piece with this horse. How did the teacher come up with this?”

“Labor and management are dizzy when they see the kinetic energy. I don’t know them, and they probably don’t know me either.”

“I bet no one in the class will do it.”

“Even Qin Feng, the super schoolmaster who ranks number one in the school all the year round, has to grind and sink in the face of this question.”

“Difficulty!”

“How can it be a difficult word?”

“…”

In an instant, the class shouted in exclamation.

Almost no one can understand, let alone have ideas, including Qin Yumo, Bai Yingying, Su Yu, Zhang Hao and others.

To this.

Physics teacher Xie Hongwei just smiled.

Ah!

Some people actually think it is not difficult for him to write a question?

Are you too floating?

Or am I unable to hold the knife?

What a joke.

If he didn’t show his hand today and asked some people to beg for mercy, others would really think he didn’t have three eyes.

Just the above question.

Not to mention these ordinary students, even he himself will not be able to do it for a while if he does not read the lesson plan.

He doesn’t believe…

This time Jiang Nan can still handle it.

A trace of pride flashed in his eyes, and Jiang Nan said to the audience: “I’ll give you the chalk. Come up and see the solution. As long as you can solve it before get out of class ends, even if you are really good.”

Ah!

Solve it before get out of class?

Go dreaming!

It doesn’t matter whether you dare to come up or not.

This is the inner thoughts of the physics teacher at the moment.

but……

Let it go.

Jiang Nan shook his head, “Such a simple question does not need to be solved until the end of get out of class. Half a minute is enough.”

Finished!

He walked onto the podium.

Take the chalk.

“Squeaky” quickly wrote.

“Solution One…”

“First question…

“According to Universal Gravity and Newton’s Laws…”

“Total energy mivi－mw2=(mi+nm)v……”

“…”

“Because rmin=3347kmvR (10).”

“So the conjugate will hit the Blue Star in the end.”

“…”

“Second question…”

“CosB=-0, 7807 (18).”

“0=141, 32 degrees (19).”

“This is at 51 or 32 degrees north latitude.”

“…”

“Solution Two…”

“…”

Half a minute?

Do not……

Fart for half a minute.

Estimated to be twenty seconds.

Jiang Nan wrote the answer not to say, not even one solution, but two solutions.

That action…

It was really done in one go, smooth and not separated, like running clouds and flowing water, and everyone was dazzled.

“Fuck… trough… trough…”

Finally, in front of all the children’s shoes, Xie Hongwei, the physics teacher, couldn’t help but exploded directly.

f*ck!

He was already shocked by this scene and didn’t know what words to use to describe his inner thoughts at the moment.

The only thing you can do is not stop.

Even him.

The children’s shoes underneath are even more so.

The faces of each one are quite wonderful.

Just because…

They can’t even understand the answer!

This is simply tadpole text!

Holy book!

You evildoer, quickly collect your magical powers!

the other side.

Jiang Nan ignored the shock of everyone.

After writing the last word, he threw the chalk head casually, but dropped it into the chalk box accurately and accurately.

That action…

It can’t be said that it is not chic.

Then clap your hands.

Go off the podium and return to your position.

For a while…

Seeing that everyone did not react.

Including the physics teacher was also stunned on the stage.

Jiang Nan had to remind him aloud: “Teacher, I have finished the question, you can see the process and the answer, right?”

“Ah… well… I… look at…”

Hearing this, Xie Hongwei finally recovered, and immediately turned out the lesson plan to compare with the blackboard.

It’s okay not to compare.

One comparison.

His whole body is going to stand upside down.

The whole person is going to be stupid.

Just because…

The answer is 100% correct.

Jiang Nan’s problem-solving ideas.

It is more refined and concise than the lesson plan.

Especially the second solution.

There is no lesson plan either!

Could it be a new solution that Jiang Nan came up with?

It’s absolutely unbelievable.

Awesome!

“Good! Good! Good!”

This is what Xie Hongwei slapped his thigh and shouted.

At this moment, he was really excited, too excited, just like a big fool.

He never underestimated Jiang Nan anymore.

on the contrary.

When he looked at Jiang Nan again, there was a raging fire in his eyes, as if he had seen a rare treasure.

If he weren’t still in class, he would like to directly pull Jiang Nan to find his head teacher and the head of the physics group.

Regarding this, Jiang Nan didn’t care, but asked calmly, “Teacher, do you still have to ask questions?”

Questions?

A fart question.

This is already Xie Hongwei’s killer.

But Jiang Nan didn’t feel embarrassed at all.

What’s the use of asking questions again?

so……

Xie Hongwei directly waved his hand: “No more.”

“Then it’s okay if I don’t hand in my homework?”

“It’s okay, you don’t have to pay it anymore.”

“Then I sleep in class?”

“You can sleep…”

“…”
