Problem 2 A turntable is initially rotating at 33 revolutions per minute.

Problem 2 A turntable is initially rotating at 33 revolutions per minute. When the record is over, it takes it 5 s to come to a stop. Assuming that its moment of inertia is I = 0.2 kg m, (a) What is the turntable's initial angular velocity, in rad/s? (b) What is the angular acceleration (assumed constant) as it slows down? (c) What is its initial kinetic energy? (d) How much work has to be done on the turntable to bring it to rest?
