Find the child potential energy

Reference no: EM13710539

Solve the 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)?

Please, show work so I can understand the concept. Thanks.
