A fan blade rotates with angular velocity given by ?z(t)= ? ? ? t2, where ? = 4.60rad/s and? = 0.795rad/s3
Part A Calculate the angular acceleration as a function of time.
Part B Calculate the instantaneous angular acceleration ?z at t0 = 2.8s.
Part C Calculate the average angular acceleration ?av?z for the time interval t=0 to t0 = 2.8s.
