A uniform cylindrical turntable of radius 1.9 m and mass 30.0kg rotates counterclockwise in a horizontal plane with an initial angular speed of 4pi rad/s. The fixed turntable bearing is frictionless. A lump of clay of mass 2.25kg and negligible size is dropped onto the turntable from a small distance above it and immediately sticks to the turntable at a point 1.80m to the east of the axis. A. Find the final angular speed of the clay and turntable. B. Is the mechanical energy of the turntable-clay system constant in this process? C. Is the momentum of the system constant in this process? Explain your answer.
