Question

a body of mass 100kg is lifted up by 10m find . 1)amount of workdone 2)potential energy of the body at the height (g=10m/s)

Answer 1

P. E= m×g×h
P. E=100×10×10
P. E=10000 J

Answer 2

1. We know,
work done=m*g*h
=100kg *10m/s *10m
=10000 kg m/s²
=10000J

2.Since distance at height=10m
By the formula of potential energy.....
P. E= mgh= 10000J
