Question:

A 25.0 kg child on a 2.00-m-long swing is released from rest when the ropes of the swing make an angle of 30.0 ^o with the vertical.

(a) Neglecting friction, find the child’s speed at the lowest position.

(b) If the actual speed of the child at the lowest position is is 2.00 m/s, what is the mechanical energy lost due to friction?
