Centripetal Acceleration Rotor

A centrifuge rotor is accelerated from rest to 20,000 rpm in 5.0 min:
(a) What is the current angular speed (omega) in rad/sec?
(b) What is the angular acceleration (alpha)rad/sec^2?
(c) If the centrifuge is modeled as a cylinder of radius 0.10 m and mass 2.0 kg,
what torque is applied to make it spin?
