Complete question:

A ball with a weight of 0.5 kg is sitting on a shelf that is 3 meters high. What is the gravitational potential energy of the ball ?

Help me! This is 8th grade sci btw

the gravitational potential energy of the ball is is 14.7 J.

Explanation:

mass of the ball, m = 0.5 kg

height above the ground on which the ball is sitting, h = 3 m

The gravitational potential energy of the ball is calculated as follows;

P.E = mgh

P.E = 0.5 x 9.8 x 3

P.E = 14.7 J

Therefore, the gravitational potential energy of the ball is is 14.7 J.
