The angular acceleration of a wheel is a = 6.0r - 4.0(2, with a in radians per second-squared and t in seconds. at time ( = 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).
