Compute all parts of given question:
Question: A 4.0 x 102 N child is in a swing that is attached to a pair of ropes 2.00 m long. Take the child's position when the ropes are horizontal to be zero gravitational potential energy.
Part A: Find the child's potential energy when the child is at the lowest point of her circular trajectory.
Part B: Find the child's potential energy when the ropes make 30.o angle with respect to the vertical.
Part C: Based on these results, which position has the higher potential energy, a) or b)?
I want help to find the child's potential energy when the child is at the lowest point of her circular trajectory.
