The angular position of a point on the rim of a rotating wheel is given by è = 8.0t  3.0t2 + t3, where è is in radians and t is in seconds.
(a) What is the angular velocity at t = 5 s?
___________rad/s
(b)What is the angular velocity at t = 7.0 s?
_________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

You cant do it, its impossible.
