Starting from rest at t = 0 s, a wheel undergoes a

Starting from rest at t = 0 s, a wheel undergoes a constant angular acceleration. When t = 2 s, the angular velocity of the wheel is 4.8 rad/s. The acceleration continues until t = 19 s, when the acceleration abruptly changes to 0 rad/s. Through what angle does the wheel rotate in the interval t = 0 s to t = 36 s?
