A disk rotates with constant angular acceleration about an axis passing through its center of mass. At an instant, its angular speed is measured to be 20.0 [rad/s]. What is the angular speed of the disk after 2.00 [s] if it has revolved by 60.0 [rad] during this time interval? A. 10.0 [rad/s] B. 20.0 [rad/s] C. 30.0 [rad/s] D. 40.0 [rad/s]
