Question

What is the potential energy of the body of 5kg, when it is lifted through 20m?

Answer 1

Answer:

980J

Explanation:

given that,

mass of the body,m =5kg

height raised,h=20m

acceleration due to gravity is not given,so we have to take

acceleration due to gravity=9.8m/s²

potential energy of the body,

P.E=mgh

=(5)(9.8)(20)

=980J
