in an old fashioned well, a bucket is suspended over the well shaft by a winch and rope. this winch includes a solid cylinder with moment of inertia I=56 kgm^2 and radius R=2 m and rotates without friction about a horizontal axis. the bucket (mass m=14kg) must descend a height h=10m to reach the water. we assume that the rope is massless and that it unwinds without slipping. the bucket is released from rest. find the speed v of the bucket just before the bucket hits the water using the energy method.
