What law of motion corresponds with this statement? "a rifle kicks." first law second law third law

Newtons first law. It would remain at rest unless someone (a force) makes it move.

A rifle kick is when you fire a projectile and you feel a force pushing agains your hand. Rifles normally have heavier projectiles so there is more force pushing back against you. example, if you were sitting on a spinny chair with wheeles and your friend is sitting on another, and you push each other while on the chair, you will both go backward, but the lighter person will go back more.

for every action, there is an equal and opposite reaction

that is the third law, also said as: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body."
