The angular position of a point on the rim of a rotating wheelies given by theta=4.0t -3.0t2 +t3, where theta is in radians and tis in seconds. What are the angular velocities at a) t=2.0sb) t=4.0s? c) what is the average angular acceleration for the time interval that begins at t=2.0s and ends at t=4.0s/ What are the instantaneous angular accelerations at d) the beginning and e) the end of this time interval?
