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. Complete the table below to compare the impulse each puck experiences from the collision. Remember, impulse is an object's change in momentum.
