UMCL Mlllrl'l Cull\" Hanna annular-Inn. 'L A turntable is a uniform disc of mass 12 kg and radius 1.3 )r 101 m. The turntable is spinning at a constant rate of 12:13.5 HZ . The motor is turned off and the turntable slows to a stop in 8.0 s with constant angular deceleration. Find the {a} moment of inertia of the turntable: [b] initial rotational kinetic energy; [c] angular deceleration of the turntable while it is slowing down: {d} total angle in radians that the turntable spins while slowing down; and {e} magnitude of the frictional toro ue. 2- The flywheel of an engine has moment of inertia 2.30 Jig-m2 about its rotation axis. What constant torque is required to bring it up to an angular speed of 400 rew'min in 150 5, starting from rest
