A uniform cylindrical turntable of radius 1.90 m and mass 28.2 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 2.49 kg and negligible size is dropped onto the turntable from a small distance above it and immediately sticks to the turntable at a point 1.80 m to the east of the axis.

(a) Find the final angular speed of the clay and turntable.

Magnitude	rad/s
Direction	---Select--- counterclockwise clockwise

(b) Is mechanical energy of the turntable-clay system conserved in this process?
---Select--- no yes
What, if any, is the change in internal energy?

Your response differs from the correct answer by more than 100%. J

(c) Is momentum of the system conserved in this process?
---Select--- No yes
What, if any, is the amount of impulse imparted by the bearing?
  kg · m/s
