If the motor of Sample Problem 7/2, repeated in Prob. 7/11, reaches a speed of 3000 rev/min in 2 seconds from rest with constant acceleration, determine the total angular acceleration of the rotor and disk second after it is turned on if the turntable is rotating at a constant rate N = 30 rev/min. The angle γ = 30° is constant.
