Question

A monkey weight 50 kg climbs up a vertical tree of height 300 metre, how much potential energy does
it gain?( g= 9.8 metre per second square) ​

Answer 1

Answer:

Given,

mass of monkey = m = 50 kg

height = h = 300m

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

work done on the boy = gain in potential energy

P.E=mgh

P.E=50×9.8×300

P.E=147,000 kJ

so, potential energy gained by monkey is 147,000 KJ.
