Question

A ball with a mass of 15kg sits at rest on

top of a tall 5m table. What is the
gravitational potential energy of the ball?
a

Answer 1

735 J

Step-by-step explanation:

Formula

Gravitational Potential Energy (GPE) = mgh

Given

• m = 15 kg
• h = 5 m
• g = 9.8 m/s

Solving

• GPE = 15 x 5 x 9.8
• GPE = 75 x 9.8
• GPE = 735 J
