Question

A ball of mass 0.20 kg is kept at rest at a height 5 m. (acceleration due to gravity= 10 m/s²) Find its potential energy. Now the ball is allowed to fall freely. Find out kinetic energy and the speed of the ball just before it hits the ground. Choose the option with correct answers. *

Answer 1

Answer:

m=0.20kg

h=5m

g=10m/s^2

P.E=mgh

=0.20*5*10

=10J
