A hollow ball of radius 0.5 m and mass 4.5 kg is rolling without slipping on a level surface at a constant speed of 4.0 m/s. The ball rolls up a 400 ramp and eventually stops before rolling back down. (the moment of inertia of a hollow ball of mass M and radius R is (2/3)MR^2)

Find:

(a) the angular (rotational) speed of the ball (in rad/sec) just before it begins to move up the ramp

(b) the rotational kinetic energy of the ball (in J) right before it begins to move up the ramp
