Question

what is the gravitational potential energy of a 61.2 kg person standing on the roof of a story building if each story is 2.5 meters high

Answer 1

Answer:

So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

hope this will help you

Answer 2

Given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.
