Question

A 2 kg block rests on a shelf that is 3m tall. What is the Gravitational Potential Energy of the block? The forse of gravity on Earth (g) is equal to 9.8 m/s^2

Answer 1

58.8Joules

Explanation:

The gravitational potential energy = mgh

m is the mass = 2kg

g is the acceleration due to gravity = 9.8 m/s²

h is the height = 3m

Substitute;

GPE = 2 * 9.8 * 3

GPE = 6 * 9.8

GPE = 58.8Joules

Hence the Gravitational Potential Energy of the block is 58.8Joules
