The angular position of a point on the rim of a rotating wheel is given by θ = 6.0t - 2.0t2 + t3, where θ is in radians and t is given in seconds.
(a) What is the angular velocity at t = 2 s?
rad/s
(b)What is the angular velocity at t = 4.0 s?
rad/s
(c) What is the average angular acceleration for the time interval that begins at t = 2 s and ends at t = 4.0 s?
rad/s2
(d) What is the instantaneous angular acceleration at the beginning of this time interval?
rad/s2
(e)What is the instantaneous angular acceleration at the end of this time interval? rad/s2 (at the end)
