Use conservation of energy to determine the angular speed of the spool shown in the figure below after the 3.00-kg bucket has fallen 4.60 m, starting from rest. The light string attached to the bucket is wrapped around the spool and does not slip as it unwinds. A 3.00-kg bucket is suspended from the free end of a string wrapped around a 5.00-kg spool. The spool has a radius of 0.600 m and is oriented such that it rotates about a horizontal axle passing through its center.
