The body begins from rest.
At this point the initial velocity is equal to zero.
The body accelerates downwards by a constant acceleration of the gravitational acceleration.
It attains a maximum speed V on reaching the surface.
On reaching the surface it bounces back at the final velocity and decelerate constantly by the gravitational acceleration until the final speed is 0.
We can represent this in a graph as shown in the attached image.
