Question

There is a 2kg ball resting on the roof of a house that is 8m high. What is the balls gravitational potential energy? GPE- mgh. G-9.8 m/s^2

Answer 1

156.8 J

Step-by-step explanation:

The gravitational potential energy of a body can be found by using the formula

GPE = mgh

where

m is the mass

h is the height

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

From the question we have

GPE = 2 × 9.8 × 8 = 156.8

We have the final answer as

156.8 J

Hope this helps you
