Question

A rook is dropped from a high tower and falls freely under the influence of gravity. Which one of the following statements concening the rock as it falls is true? Neglect the effects of air resistance. The rock will gain an equal amound of kindetic energy during earch second. The rock will gain an equal amount of speed for earth meter through which it falls. The rock will gain an equal amount of momentum during each second. The rock will gain an equal amount aof momentum for each meter through which if falls.

Explanation / Answer

The rock will gian an equal amount of momentum uring each seconds

because during each sec speed will increase by g*t = (9.8 m/s^2)*(1sec) = 9.8 m/s

so momentum P = mv will also increase in same amount in each second
