The 50kg flywheel has a radius of gyration of ko 200 mm abo

The 50-kg flywheel has a radius of gyration of k_o = 200 mm about its center of mass, and is at rest. The wheel is then subjected to a torque M that rises uniformly from 0 to 25 N middot m over its first revolution, then maintains a constant torque of 25 N middot m. What is the angular velocity of the wheel after the wheel has completed 3 revolutions.
