The distance between the monkey and the shooter is A. The monkey’s height on the tree was H, and the time taken for the bullet to reach the tree branch is t. The height of the bullet then was h(i), and the height of the monkey h(j). The speed of the bullet is v, the force of gravity is g. Assume no air resistance. |

Correct answer. People would normally assume that the bullet would be too fast and won’t be affected by gravity. But in fact, the monkey’s falling down to the ground at terminal velocity<ref>A very important part of physics. When an object falls due to gravity, air resistance will increase until the object falls at constant speed. That is [http://en.wikipedia.org/wiki/Terminal_velocity Terminal Velocity]</ref>. At this moment, the height of the bullet h(i) and the height of the monkey h(j) has nothing to do with the bullet speed V, but only related to the force of gravity g and time t. Sensei deliberately added unnecessary symbols in the answer, but as expected of Himeji-san, that was a good answer. |
