A uniform cylindrical turntable of radius 1.90 m and mass 28.2kg rotates counterclockwise in a horizontal plane with an initialangular speed of 4Ï€ rad/s. The fixed turntable bearing isfrictionless. A lump of clay of mass 2.49 kg and negligible size isdropped onto the turntable from a small distance above it andimmediately sticks to the turntable at a point 1.80 m to the eastof the axis.
(a) Find the final angular speed of the clay and turntable.
| Magnitude | Â Â rad/s |
| Direction | ---Select--- counterclockwise clockwise |
(b) Is mechanical energy of the turntable-clay system conserved inthis process?
---Select--- no yes Â
What, if any, is the change in internalenergy?
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 Â
What, if any, is the amount of impulse imparted by thebearing?
