A uniform cylindrical turntable of radius 2.00 m and mass 26.0 kg rotates counterclockwise in a horizontal plane with an initial angular speed of 4π rad/s. The fixed turntable bearing is frictionless. A lump of clay of mass 2.47 kg and negligible size is dropped onto the turntable from a small distance above it and immediately sticks to the tumtable at a point 1.90 m to the east of the axis. (a) Find the final angular speed of the clay and turntable. magnitude rad/s direction (b) Is mechanical energy of the turntable-clay system constant in this process? Yes No What, if any, is the change in internal energy? x Your response differs from the correct answer by more than 10%. Double check your calculations. J (c) Is momentum of the system constant in this process? Yes No What, if any, is the amount of impulse imparted by the bearing? x magnitude Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. kg⋅m/s direction
