The correct response is:
Football player #5 exerts an action force against player #29. Player #29’s force is a reaction force against player #5.
In this scenario, the action force is the force that player #5 exerts on player #29, and the reaction force is the force that player #29 exerts back on player #5. This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
