Spring 2008 PP10601-4 The angular position of a point on the rim of a rotating wheel is given by q = 4.0t - 3.0t 2 + t 3 , where q is in radians and t is in seconds. What are the angular velocities at (a) t = 2.0 s and (b) t = 4.0 s? (c) What is the average angular acceleration for the time interval that begins at t = 2.0 s and ends at t = 4.0 s? What are the instantaneous angular accelerations at (d) the beginning and (e) the end of this time interval? PP10601-7 A diver makes 2.5 revolutions on the way from a 10-m-high platform to the water. Assuming zero initial vertical velocity, find the diver's average angular velocity during a dive. PP10601-8
