A large disk rotates from rest in a horizontal plane with a constant angular acceleration of 3 rad/s². You know that during a 5 s interval later in time, it turns through 60.0 rad. (a) What is the angular velocity of the wheel at the beginning of that 5 s interval? (b) How long has the wheel been turning before the beginning of the 5 s interval
