_________rad/s

(c) What is the average angular acceleration for the time interval that begins at t = 5 s and ends at t = 7.0 s?
_____________rad/s2

(d) What is the instantaneous angular acceleration at the beginning of this time interval?
_____________rad/s2

(e)What is the instantaneous angular acceleration at the end of this time interval?
_____________ rad/s2
