A disk rotates about its central axis starting from rest and accelerates with constant angular acceleration. At one time it is rotating at 11 rad/s; 75 radians later, its angular speed is 22 rad/s. Calculate (a) the angular acceleration (rad/s^2), (b) the time required to complete the 75 radians, (c) the time required to reach the 11 rad/s angular speed, and (d) the number of radians from rest until the time the disk reaches the 11 rad/s angular speed.
