Question

There is a bell on top of a tower that is 45 meters high. The bell has a mass of 20 kg. Calculate its potential energy.

Answer 1

9000 Joules

Step-by-step explanation:

Potential energy = mass x acceleration due to gravity x height

mass = 20kg

acceleration due to gravity = 10m/s2

height = 45 meters

20 x 10 x 45 = 9000 Joules
