Many people are familiar with the fact that a rifle recoils when fired. This recoil is the result of action-reaction force pairs. A gunpowder explosion creates hot gases that expand outward allowing the rifle to push forward on the bullet. Consistent with Newton's third law of motion, the bullet pushes backwards upon the rifle. The acceleration of the recoiling rifle is ...
a. greater than the acceleration of the bullet.
b. smaller than the acceleration of the bullet.
c. the same size as the acceleration of the bullet.
Answers
Answer:
The force on the rifle equals the force on the bullet. Yet, acceleration depends on both force and mass. The bullet has a greater acceleration due to the fact that it has a smaller mass. Remember: acceleration and mass are inversely proportional.

Answer:
The acceleration of the recoiling rifle is smaller than the acceleration of the bullet.
EXPLANATION:
The recoil in a gun is caused due to the forward momentum of the bullet. The force with which the bullet is fired is stable by the recoil of the gun. So the recoil follows Newton's third law of motion.
Newton's Third Law: For every action, there is an equal and opposite reaction.
By Newton's third law of motion, the acceleration of the rifle equals the force that the bullet applies on the rifle divided by the mass of the rifle. The two forces are equal, but since the mass of the rifle is much greater than the mass of the bullet, the acceleration of the rifle is smaller than the bullet's acceleration
