Answer 1

Answer:

Newton's third law states that in a system, there are equal and opposing forces. Hence, when a constituent of a system leaves it, it leaves its so called trace marks behind a.k.a momentum in opposite direction. Hence, Gun goes back in proportion to its mass and bullet moves forward due to its exploding gunpowder.
