Question

A boy of 4000 g walks and climbs a building of height 8000 cm find the potential energy when the boy is on top of the building ?

Answer 1

3136J

Explanation:

mass(m)=4000g=4kg

height(h) =8000cm=80m

g(acceleration due to gravity)=9.8m/s^2

potential energy=mgh=4×9.8×80=3136Joule

Answer 2

Answer:

3136J

Explanation:

Mass = 4000g = 4kg

Height = 8000cm = 80m

Gravity = 9.8m/s²

so, Potential Energy = MGH = 4×80×9.8 = 3136
