Question

The object is dropped in a vertical downward direction on the ground. What is the change in speed after cutting the distance equal to the maximum height d?​

Answer 1

Using the equation v^2−u^2 =2as

We get v^2 = 2as Since u=0

Clearly the graph will be parabolic.

The velocity will be negative while the ball falls while it will be positive when it bounces back i.e. they will have opposite direction, also the maximum height will be

d/2
