A 290 kg child on a 100 m long swing is released from rest, Ask an Expert

Academics

A 29.0 kg child on a 1.00 m long swing is released from rest when the ropes of the swing make an angle of 31.0° with the vertical.

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

(b) If the speed of the child at the lowest position is 1.50 m/s, what is the mechanical energy lost due to friction?
