A ball of mass m is thrown vertically up with an initial velocity so as to reach a height h. The correct statement is:

 a. Potential energy of the ball at the ground is mgh.

 b. Kinetic energy to the ball at the ground is zero.

 c. Kinetic energy of the ball at the highest point is mgh.

 d. The potential energy of the ball at the highest point is mgh.

Solutions:

The correct statement is

‘potential energy of the ball at the highest point is mgh.
