A ball is held at rest at the top of a hill. The ball is then released and starts rolling down the hill. At the bottom it reaches level ground and keeps rolling along the ground. Defining the level ground as zero height, select from the list below what types of energy the ball has at the top of the hill:

Electrostatic Potential Energy

Rotational Kinetic Energy

Gravitational Potential Energy

Kinetic Energy

Gravitational Potential Energy

Explanation:  

a ball is held rest at the top of hill  

gravitational potential energy will store due to its height  

it.   and  body will start move downward and its potential energy will convert into kinetic energy due to motion of body

at the ground level it will stop and potential energy will became zero and kinetic energy get convert into internal energy due to collisions
