(a) What was the angular acceleration during this time?

____rad/s2

(b) What was the average angular velocity?

____ rad/s

(c) What is the instantaneous angular velocity of the disk at the end of the 5.0 s?

____rad/s

(d) Assuming that the acceleration does not change, through what additional angle will the disk turn during the next 11.0 s?

____rad
