Use conservation of energy to determine the angular speed of the spool shown in Figure P8.36 after the 3.00 kg bucket has fallen 3.20 m, starting from rest. The light string attached to the bucket is wrapped around the spool and does not slip as it unwinds.

The Figure shows the spool to have a mass of 5.00kg and a radius of 0.600m.
