3) a defense football player on one team tackles the other team’s quarterback, who is running down the field. the quarterback is pushed to the ground by the defensive player. 4) apply newton’s first law to explain what happened?

Newton's first law says that an object at rest tends to stay at rest while an object in motion stays in motion at a constant velocity unless acted upon by an outside force so the amount of force behind the defensive football player (N) was greater than the quarterback's so he was able to over power him which is also called unbalanced forces

Edit the post so i can see the letters for each answer, and increase the points required so i'd be able to answer it.
