uniform cylindrical turntable of radius 1.80 m and mass 30.4 kg rotates counterclockwise in a horizontal plane with an initial angular speed of 4x rad/s. The fixed turntable bearing is frictionless. A lump of clay of mass 2.29 kg and egligible size is dropped onto the turntable from a small distance above it and immediately sticks to the turntable at a point 1.70 m to the east of the axis. (a) Find the final angular speed of the clay and turntable. magnitude rad/s direction counterclockwise ✔ (b) Is mechanical energy of the turntable-clay system constant in this process? Yes o No What, if any, is the change in internal energy? (c) Is momentum of the system constant in this process? Yes o No What, if any, is the amount of impulse imparted by the bearing? magnitude kg. m/s direction north
