A 39.5 N child is in a swing that is attached to ropes 2.01 m long.

What is the gravitational potential energy when the child is at the bottom of the circular arc?

I thought that you would multiply the force given by 2.01 m, but the answer I calculated was incorrect.

    GPE is relative to some point. Normally, that point would be the lowest point, so the kid is there, and GPE is zero.
