Determine the speed the child will have at the bottom of arc

Reference no: EM13328022

A 75- kg child sits in a swing suspended with 3.2- m-long ropes. The swing is held aside so that the ropes make an angle of 40 o with the vertical. Use conservation of energy to determine the speed the child will have at the bottom of the arc when she is let go.
