An ice rink gives us a good opportunity to think about forces and momentum. Consider two identical hockey pucks, A and B. Puck A is in motion travelling in the

positive direction towards Puck B which is at rest. The ice surface is frictionless, so there are no resistive forces acting on the either puck. Puck A has a momentum of 3 kg m/s when it strikes Puck B. After the collision, Puck B has a momentum of 2 kg m/s. When reflecting on your answers to #3 and #4, and when thinking about the conservation of momentum in collisions in general, how does the combined momentum before the collision compare to the combined momentum after the collision? When reflecting on your answers to #3 and #4, and when thinking about the conservation of momentum in collisions in general, how does the impulse experienced by one object compare to the other object during a collision?
