Question: The angular position of a point on a rotating wheel is given by ? = 1.96 + 6.20t2 + 4.15t3, where ? is in radians and t is in seconds. At t = 0, what are
(a) the point's angular position and
(b) its angular velocity?
(c) What is its angular velocity at t = 7.97 s?
(d) Calculate its angular acceleration at t = 2.88 s.
