The angular position of a point on a rotating wheel is given by θ = 2.0 + 4.0t² + 2.0t³, where θ is in radians and t is in seconds. At t = 0, what are
(a) the point’s angular position and
(b) its angular velocity?
© What is its angular velocity at t = 4.0 s?
(d) Calculate its angular acceleration at t = 2.0 s.
(e) Is its angular acceleration constant?
