The angular acceleration of a wheel is α =6t4-4t2 with α in radians/s2 and t in seconds. At time t = 0, the wheel has an angular velocity of +2 rad/s and an angular position of +1 rad.
(a) Write expressions for angular velocity?
(in rad/s)
(b) Write expressions for angular position as functions of time (in s)?
(in rad)
