A uniform cylindrical turntable of radius 1.80 m and mass 27.2kg rotates counterclockwise in a horizontal plane with an initialangular speed of 4π rad/s. The fixedturntable bearing is frictionless. A lump of clay of mass2.39 kg and negligible size is droppedonto the turntable from a small distance above it and immediatelysticks to the turntable at a point 1.70 m to the east of the axis.
(a) Find the final angular speed of the clayand turntable.
What, if any, is the change in internal energy?
What, if any, is the amount of impulse imparted by the bearing?
