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. Below are possible free-body diagrams for puck A. Drag and drop the option that correctly models the forces acting on the puck as it travels across the frictionless ice unassisted. Free-body diagram for Puck A; Which of the diagrams correctly models the forces acting on puck B while it is at rest on the ice?
