Question

Channel picks her baby brother up out his crib after his nap. If the baby has a mass of 8.5 kg and she picks him up a distance of 0.74 meters, what is the baby's gravitational potential energy?

Answer 1

I found: `61.7J`

Explanation:

Gravitational Potential Energy `U` is:
`U=mgh`
Where:
`m=` mass`=8.5Kg`;
`h=` height`=0.74m`;
`g=` acceleration of gravity`=9.81m/s^2`.
So in your case:

`U=8.5*9.81*0.74=61.7J`
