The moment of inertia of the rotor of the medical centrifuge is I = 0.2 kg-m2 . The rotor starts from rest and the motor exerts a constant torque of 0.8 N-m on it.
(a) How much work has the motor done on the rotor when the rotor has rotated through four revolutions?
(b) What is the rotor’s angular velocity (in rpm) when it has rotated through four revolutions?
