A ball is moved on a horizontal table with some velocity. The ball stops after moving some distance. Which external force is responsible for the change in the momentum of the ball?

Consider the situation of the previous problem. Take the table and the ball as a system friction is then an internal force. As the ball slows down the momentum of the system decreases. Which external force is responsible for this change in the momentum?

A ball is given a speed v on a rough horizontal surface. The ball travels through a distance l on the surface and stops. A. What are the initial and final kinetic energies of the ball? b. What is the work done by the kinetic friction?
