No. 2 (D level): If an airplane is flying at high speed and collides with a bird, the airplane will get a hole. Why is that? Or explain the principle!
No. 3 (B level): Who is the unluckiest person on the entire site? (No answer, you need to give a reason; the most reasonable explanation wins!)
No. 4 (C level): What number Elizabeth is the current Queen of the United Kingdom?
No. 5 (Super hard SS level): If A + B = C, prove that 3 = 4, and also explain why?
No. 6 (Hard S level): In the last century, at Tsinghua Circle, who was referred to along with Zhu Ziqing as the “Tsinghua Double Qing”?
No. 7 (A level): What is a very trendy newspaper in Europe?
No. 8 (F level): Who is the author of "How the Steel Was Tempered"?
No. 9 (Hard A level): Two riders are racing on their own horses, but the competition is to see whose horse runs slower. So the two riders start riding their horses slowly. How can one win? A wise person gave them a clever plan. Later, after discussing, the two riders whip their horses and suddenly speed off.
What clever plan did the wise person teach them?

No. 2 A bird collides with an airplane. Because motion is relative, the speed of the bird relative to the airplane is the airplane's speed plus the bird's flying speed, which is very high, so the airplane will get a hole.
8th floor, I looked again, there are defects, it can't count as your achievement, in connection with strength
The faster the airplane, the greater the force on the bird, and the force acts mutually; the force of the bird on the airplane is also large.
11th floor, think again, what you did is completely wrong, right? You've substituted three conditions! In math, you're not allowed to substitute so many at once, otherwise you might as well make up your own problem.
12th floor, it can be considered correct, the answer is very close. The action of force is mutual. If a plane crashes into a bird at such high speed, conversely, isn't it like the bird is using its own speed along with the plane's speed to hit the plane? So then......
Keep it up, original poster... As long as there are more than one hundred visitors to the post, it can be highlighted...
