A 400-N child is in a swing that is attached to a pair of ropes 2.00 m long. Find the gravitational potential energy of the child-Earth system relative to the child's lowest position when 1. the ropes are horizontal, 2. The ropes make a 30.08 angle with the vertical, and 3. The child is at the bottom of the circular arc.
