Question

A 60 kg person walks from the ground to the roof of a 80 m tall building. How much increase in gravitational potential energy is there

Answer 1

Answer:

Gravitational potential energy = 44027.28 J

I hope this answers will help you and don't forget to marke me brilliance please and thank also please

Answer 2

Explanation:

Given Data:

mass = 60kg

height = 80m

g = 10m/s

To Find:

Gravitational Potential Energy = ?

Solution:

We know that:

P.E. = mgh

= 60 x 10 x 80

= 48000J

Therefore, the increase in the gravitational potential energy is 48000J
