A fan blade rotates with angular velocity given by ?z(t)= ? ? ? t2, where ? = 5.45rad/s and? = 0.835rad/s3.
a.) Calculate the angular acceleration as a function of time.
b.) Calculate the instantaneous angular acceleration ?z at t0 = 3.5s.
c.) Calculate the average angular acceleration ?av?z for the time interval t=0 to t0 = 3.5s.
