Question:

The angular acceleration of a wheel is a = 6.0t4 - 4.0t2, with α in radians per second-squared and t in seconds. At time t = 0, the wheel has an angular velocity of +2.0 rad/s and an angular position of +1.0 rad. Write expressions for

(a) The angular velocity (rad/s) and

(b) The angular position (rad) as functions of time (s).
