Question: A fan blade rotates with angular velocity given by wu (t) =Y - Bt2, where Y = 5.00 rad/s and p = 0.800 rad/s3. (a)

A fan blade rotates with angular velocity given by wu (t) =Y - Bt2, where Y = 5.00 rad/s and p = 0.800 rad/s3.
(a) Calculate the angular acceleration as a function of time.
(b) Calculate the instantaneous angular acceleration a z at t = 3.00 s and the average angular acceleration a avc for the time interval t = 0 to t = 3.00 s. How do these two quantities compare? If they are different, why are they different?
