If you think that your school is asking too complicated problems in physics, then I want to upset you. Chinese education is much harder than Russian, so the exercises there are appropriate. We offer you a task that at first glance seems absurd. But she can be caught by a Chinese student who is taking an exam in high school. What color is the bear that fell into the pit?
Answer options
The task has answer options. Polar bear, brown, black, black-brown or gray. Before finding out the correct answer, I suggest thinking a bit and remembering the physics course.
The solution of the problem
I suggest recalling a formula that will allow us to know the acceleration of gravity.
S = g2/2
From this formula, g will be 9.8085 m / s2. Now we need to find out at what latitude such acceleration can be achieved. In the Southern Hemisphere, there are no bears at this coordinate, so we can assume that the pit was dug somewhere in the Northern.
If the bear was able to fall into the pit, then it was big enough. How many more such huge animals live on land? The answer to this question gives us yet another assumption: the hole was dug specifically for the bear. Also, the trap was located on the ground, which means that the animal is land. Therefore, the correct answer is either a brown bear or a black one. The rest are not land.
Given the size of the bear, which is about 20 meters, we can assume that the pit was dug in soft soil. Brown bears live only in places of hills and mountains. There is no soft ground in such places. Accordingly, the answer to the problem will be a black bear.
Conclusion
This is an excellent task, which slightly affects the knowledge of physics and a little - geography. We connect the logic and find the correct answer. I was interested to find the answer to this problem, but I think that if such an exercise were in my exam, then I would definitely not pass it. So it’s good that we do not live in China.
