In Exercise 13, suppose the wheel took 1.20 s to stop after it was bumped. Assume as you face the plane of the wheel, it was rotating counterclockwise. During this time, determine
(a) The average angular speed and tangential speed of the pebble,
(b) The average angular speed and tangential speed of a piece of grease on the wheel’s axle (radius 1.50 cm), and
(c) The direction of their respective angular velocities.
