A ball of mass m=1.3kg is dropped from a height of 1.5 meters onto the ground, where it bounces perfectly. It continues to bounce this way for a long time. Plot the kinetic energy, gravitational potential energy, and total energy of the ball vs. time for a few bounces.
a) The bounces are instantaneous
b) The bounces take a short but finite amount of time.

Gravitational potential energy=mgh (mass*gravity*height)
Kinetic energy=(1/2)*(m)*v^2
Total energy=Kinetic + Gravitational

Hope it helps
