Question

A circular disc with a radius of gyration of 200 mm and a mass of 15 kg is rotating in the clockwise direction with an angular velocity of 5 radians per second. From the time t=0 seconds if the disc is subjected to a counterclockwise moment of 9t, where t is the time in seconds, deternmine the direction and magnitude of angular velocity of the disc at time t=10 seconds.

Answer 1

ωf = -2995 rad/s (counterclockwise)
