Answer to Question #96004 in Physics for reem

Question

A ball is thrown straight up from a point 2 m above the ground. The ball reaches a maximum height of 3 m above its starting point and then falls 5 m to the ground. When the ball strikes the ground, what is its displacement from its starting point?

Answer 1

The displacement from its starting point:

$$s=h_f-h_i=0-2=-2\ m.$$

So, its displacement from its starting point is 2 meters downwards.
