We have that the  gravitational potential energy at height 1m  is mathematically given as

Ep=8 J.

Potential energy

Question Parameters:

Object A has a gravitational potential energy of 24 joules

it rests on a shelf 5 m above the ground

it rests on a shelf 10 m above the ground

Generally, the equation for the gravitational potential energy Ep mathematically given as :

Ep=m*g*h

where

  • m is the mass of the body,
  • g=9.81 m/s²
  • h is the height of the body.

Therefore

m=Ep/(g*h)=

m=24/(9.81*3)

m=0.82 kg

Gravitational potential energy

Ep=0.82*9.81*1

Ep = 8 J
