Question

A man with a weight of 100 N is located

25 meters above a street. How much
potential energy does the man have?

Answer 1

Given,

mass of man = 100 N = 10 kg

height = h = 25m

since the man does not move anything with his force, work done by him is zero

work done on the man = gain in potential energy

P.E=mgh

P.E=10×9.8×25

P.E=2.45KJ

Step-by-step explanation:

so, potential energy gained by man is 2.45 KJ
