A bucket of water with total mass 23Kg is attached to arope, which in turn is wound around a 0.050m radius cylinder,with crank, at the top of a well. The moment of inertia of theccylinder and crank is 0.12Kg m2. The bucketis raised to the top of the well and released to fall back into thewell. What is the kinetic energy of the cylinder and crank atthe instant the bucket is moving with a speed of 8.0 m/s?
