The partial schematic diagram of the Shougang Ski Big Air at the 2022 Winter Olympics is shown in the figure. The athlete slides freely from a standstill at A to jump from B, point C is the lowest point between A and B, and the height difference between A and C is H. It is required that the pressure on the skis when the athlete passes through one point is not more than k times the gravity on himself, and the athlete is regarded as a mass point during the exercise and all resistance is ignored, then the radius of this section of the arc slope at point C should not be less than ()

A:XXXX

B:XXXX

C:XXXX

D:XXXX

"Fack! Fack! Fack! Gordon broke down and yelled.

Just now, Gordon suddenly became interested, because he found out through the memory of the original body that the physics of the original body seemed to be very powerful.

As a result, I opened a set of test papers casually, and I didn't know the second question.

Seeing the irritable Gordon, Melissa gently got into his arms and comforted: "It's okay, we can learn slowly, I'll teach you." ”

While studying, Gordon slowly injected the divine power of the horse charm into Melissa's body to repair the physical damage caused by yesterday's "exercise".

-----------------

A week passed quietly.

Uncle Ben also moved home from the hospital because he was worried about financial problems.

Anyway, most of his wounds have miraculously recovered, and there is no problem at all in moving home, just take some anti-inflammatory drugs.

That evening, Peter rang the doorbell with a present.

Gordon opened the door and found it Peter, with a carton of milk in his hand.

"Hi Gordon, this is a little bit of my heart, you know, Uncle Ben spent a lot of money on hospitalization, so my financial situation is not very good."

Peter entered the door and placed the milk on the table.

"Thank you very much for your milk, Melissa is going to buy milk recently."

Gordon poured Peter a glass of warm water and asked, "How is Uncle Ben?" ”

"Thank you Gordon, thanks to you, Uncle Ben is recovering well!" Peter said gratefully.

"Did you find the man?"

Peter naturally knew who Gordon was asking, and shook his head, "I've been looking for the past two days, and not only did I not find it, but the police also noticed me. ”

Gordon quipped, "That's right, the chivalrous Spider-Boy with a hood and an old-fashioned trench coat, hahaha." ”

"I just finished making a suit for myself, believe me, Giant!"

During this time, Peter was fighting crime while looking for the man with the star tattoo on his wrist.

In order to facilitate his movements, he made himself a fiber spider suit with reference to yoga clothes.

"Please call me Spider man in the future!"

Because Ben Parker is not dead, Peter is not as depressed as in the original books.

Coupled with the fact that Ben Parker is recovering well from his injury, Peter seems to be in a good mood.

At this time, Melissa came down from the upper floor, originally planning to receive a glass of water, but she did not expect Peter to be there.

"Hey, Melissa, come and see Spider Boy!" Gordon laughed.

“Σ(⊙▽⊙“a？ ”

Peter looked at Melissa and then at Gordon.

The meaning is self-evident, you just exposed my identity like this?

Gordon flew forward and hugged Melissa down, and Peter immediately understood that Gordon was not hiding his superpowers.

"I think people who love each other shouldn't have any secrets, secrets have a price, they were before and will not change in the future."

Hearing Gordon's words, Peter fell silent, Aunt May had said similar things to him in the past two days, after all, he came home every day with a blue nose and a swollen face.

"Hello Peter, is it true that Gordon said you can squirt spider silk?"

"No, it's not that I can spit spider silk, I researched it myself." As much as he spoke, Peter leaked out the spider silk launcher.

"By the way, Gordon, do you need me to make you a uniform?" Peter asked.

"No, do you think I'm going to fight criminals when I'm idle, just like you?"

Gordon wasn't in the mood to fight criminals every day, and he didn't have to be a criminal to make the citizens of New York City thank God.

Peter doesn't really realize what kind of person Gordon is at this point, and Gordon only helps him because he's Spider-Man, not because Gordon is good.

Peter was momentarily speechless, "Don't you want to help others?" You also said that with great power comes great responsibility! ”

"My abilities are indeed powerful, but my responsibility is limited to making the people around me happy!"

Melissa smiled and snuggled into Gordon's arms.

Peter felt that he was full of dog food, and the sour smell of love drove him away all the time.

"OK, I wish you happiness, I'm going to go back to that man!"

"Humiliated" Peter left the Gordon house.

Back home, Peter put on his newly made suit, put on his backpack, and wandered around New York.
