Two football players collide during a game. Player A weighs considerably more than player B and therefore must have more mass

than player B. When the players collide, which player exerts a larger force on the other?

O It depends on the speeds; the player who is moving faster will apply the larger force to the other.

Player A applies a larger force to B than B applies to A.

Both players apply the same size force to each other (forces of the same magnitude).

Player B applies a larger force to A than A applies to B.

Correct. This is predicted by Newton's third law. Since the players have different masses, the effect that the force has on them

will not be the same, but the force each applies to the other is the same size.
