When a catcher in a baseball game grabs a fastball thrown at 90 miles an hour (that is 40 m/s), his hand and glove recoil from the catch.  The mass of a baseball is about 0.15 kg.  The mass of his hand and mitt may be 2 kg.  What is the velocity of recoil for a completely inelastic collision if he holds onto the ball?
