Homework Help: physics

Posted by amy on Saturday, October 31, 2009 at 7:25pm.

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.
