A 27.0-kg child on a 3.00-m-long swing is released from rest when the ropes of the swing make an angle of 35.0° 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 2.90 m/s, what is the mechanical energy lost due to friction?
