Calculate how much torque is applied to the disk

Reference no: EM13261248

Starting from rest, a 12-cm-diameter compact disk takes 2.5s to reach its operating angular velocity of 1500rpm . Assume that the angular acceleration is constant. The disk's moment of inertia is 2.5×10?5kgm2.

Part A How much torque is applied to the disk?

Part B How many revolutions does it make before reaching full speed?
