Youth School: Holding the stars and embracing the moon

Chapter 197 Let Me Tell You Right Now
In the end, the three of them held plush toys in their hands and looked at Ye Xingchen.

Because now only Ye Xingchen still has circles in his hand.

Of course, at the beginning Ye Xingchen also agreed to the biggest cute bear in Lin Miaomiao's suit, which can be regarded as a "military order".

"I still don't think it will fit in the car, and we're going back to school first, and we won't be able to go home until Saturday, so you still plan to get the big one?"

Ye Xingchen wasn't making excuses for his failure, he was really afraid that there would be no place to put it, this bear was almost catching up with the two Lin Miaomiao.

However, his question did arouse Lin Miaomiao's questioning: "You can't be... you can't!"

噗

Jiang Tianhao couldn't help laughing when he heard what Lin Miaomiao said.

Deng Xiaoqi also understood what the stalk meant, and her face turned red obviously.

Ye Xingchen didn't speak either, and after giving Lin Miaomiao a hard look, he turned his head and started to loop.

Ye Xingchen is not only good at theoretical knowledge, he is not just flirting with Lin Miaomiao at school during this time, but putting theory into practice.

The ring is nothing more than a game of using a ring to set it on a fixed object.To calculate the trajectory of the ferrule, the geometric properties of the circle and the knowledge of Newtonian mechanics are required.Just determine the radius (r) and relative position of the ring.

Assume that the radius of the ring is r, and the initial position is the distance h from the top of the pole.When the ring starts to fall, gravity produces a downward acceleration (g) on ​​it, according to Newton's second law: F = m*a = m*g
Among them, m is the mass of the ring, a is the acceleration, F is the force, and g is approximately equal to 9.8 m/s^2 for the acceleration of gravity.Since the force on the ring is only gravity, the acceleration can be obtained: a = g
When the ring falls to a certain height, that is, when the distance between the center of the circle and the pole top is y, the falling position and speed of the ring can be calculated through the geometric properties of the circle.Assuming that the falling time is t and the initial velocity is 0, you can get:

y = h - 1/2*g*t^2
v = g*t
where v is the velocity of the ring when it falls.If the ring is to be placed on the rod, the condition of the ring needs to be satisfied, that is, the inner diameter of the ring is smaller than the diameter of the rod, and the speed and direction of the ring falling to the top of the rod should be properly adjusted.

Through these mathematical and physical calculations, the trajectory and speed of the falling ring in the ring game can be predicted, helping to better grasp the timing and strength of the ring.

After Ye Xingchen had completed his calculations, he missed the first lap test, and the target was not the big bear, but a Pikachu in the penultimate row.

It's not too much for a boy like me to only have Pikachu.

As a result, it was naturally a trick, and everyone hadn't reacted yet.

"I'll go, once I get into the soul, Ye Zi, it's okay, there are two tricks."

Haozi exclaimed and patted Ye Xingchen's shoulder in surprise.

At this time, the boss's face was naturally not good-looking, but because of his professionalism, he still smiled and brought Ye Xingchen the plush toy he just put on, and congratulated him: "Young man is amazing, I have been setting up a stall for such a long time, you It is the first one to win the grand prize so far."

Ye Xingchen smiled and said very politely: "Luck, luck."

"Luck is also very good, then I wish you good luck in the future." The boss smirked.

"Thank you boss, business is booming."

Although Ye Xingchen knew that the boss must be in pain right now, but since he smiled and blessed him, he couldn't lose his courtesy.

At this time, Lin Miaomiao couldn't wait to snatch the big Pikachu from behind: "Let me take a look, wow, Lao Ye, you are so lucky, so can I exchange it with you?"

Lin Miaomiao blinked her cute big eyes at Ye Xingchen.

Ye Xingchen ignored her, turned around and continued to loop.

"Hmph!" The neglected Lin Miaomiao stomped her feet angrily, and then gave Pikachu a big beating, as if she took it for Ye Xingchen.

Seeing Miaomiao's appearance, Deng Xiaoqi couldn't help laughing and said, "Okay, don't be angry, let's continue watching Ye Xingchen's performance."

At this time, the boss also stood behind and looked at this side from time to time, because he suspected that Ye Xingchen was a master and came here on purpose to mess things up, so he was ready to "drive away" Ye Xingchen whenever something went wrong.

And Ye Xingchen's subsequent performance made him put this suspicion behind him.

The remaining 23 circles are completely thrown while describing. If you say it is inaccurate, it can be thrown to the side accurately every time. You say it is accurate, but he cannot hit it.

"You've been playing with Ye Zi for a long time." Lin Miaomiao said with a little disappointment.

She originally wanted to see Ye Xingchen sweep the entire field.

Ye Xingchen still didn't speak. Under the gaze of the three of them, Ye Xingchen threw the last circle to the final grand prize.

The ring was spinning in the air. At this time, the world in Ye Xingchen's eyes was already occupied by formulas and data. His brain was spinning at a high speed, and finally came to the result.

Hit rate, [-]%.

Snapped

Then there was the sound of the plastic ring falling onto the bag containing the big bear.

The boss's heart seemed to stop for a second.

"I'm going, I got it!" Lin Miaomiao jumped up happily, "You got it, Ye Zi."

"Hold the grass, send it." Jiang Tianhao reacted first, and said to the boss, "Boss, we have caught the trap, please bring it to us, thank you."

The boss who was called was very reluctant, and came to the side of the bear in the quilt, looked left and right, and seemed to be looking for a reason not to let him take away the prize.

It's a pity that the ring landed in the middle impartially, which was outrageously accurate.

In the end, the boss reluctantly took the prize.

"Ye Xingchen, you are so good, I knew you were trying to miss it on purpose." Deng Xiaoqi said adoringly.

Lin Miaomiao also questioned this after listening to Deng Xiaoqi's words: "Speaking of which, why did you deliberately release the water? You should have set a few more just now."

"He is here to make money, not to lose money. What if you make him anxious?"

Ye Xingchen also stopped pretending at this time, Showdown explained.

Lin Miaomiao seemed to understand but half understood: "So that's how it is."

"But how do you take this bear back?"

Deng Xiaoqi was worried for a while looking at this big guy.

"Well, Miao Miao, you said just now that I just need to get the suit, and I don't have to worry about taking it back. Or, you take it?" Ye Xingchen said deliberately.

Lin Miaomiao: "What, I, I, I can't hold it, no, you can't do this, it is almost as big as the two of me."

Ye Xingchen didn't care whether he could hold it or not, after taking Pikachu and handing it to Jiang Tianhao, he also threw the bear to Lin Miaomiao, and took the opportunity to tell her in a low voice: "Now you know that I can do it, so let's not do it! !"

"Hiss!" Lin Miaomiao gasped, she forgot that this guy could hold a grudge.

Looking at Jiang Tianhao and Deng Xiaoqi who both looked helpless, Lin Miaomiao was about to cry.
