A 60.0-kg person walks from the ground to the roof of a 74.8-m tall building. How much gravitational potential energy does she have at the top of the building?

Answer»

Given:

m=60.0 kg
g=9.8m/s² (ASSUMING they haven't BUILT any extraterrestrial buildings, lol)
h=74.8 m

GRAVITATIONAL POTENTIAL Energy = mg∆h

= 60.0×9.8×(74.8-0)

= 43,982.4 J
