Question

A ball is thrown vertically upward with a kinetic energy, 100J.
What will be its gravitational potential energy at the maximum height?

Answer 1

Answer:

Explanation:

As it is  at maximum height it will have only potential energy no kinetic energy because of zero velocity. Hence P.E=mgh

But when it is on the ground it has no height from the ground hence P.E is zero where K.E has a value of mgh because energy is conserved at every point.

Hence, option D is the correct answer.
