Emily uses a rifle to shoot a bullet at a target. The bullet has a mass of 13 grams. The rifle has a mass of 3,500 grams. When she shoots, the bullet accelerates 850 m/s2. According to Newton’s third law of motion, the bullet is exerting the same force on the rifle. Why doesn’t the rifle accelerate 850 m/s2?

The force of the bullet is exerted in the same direction, toward the target.
The mass of the rifle is much greater than the mass of the bullet.
The mass of the bullet is much greater than the mass of the rifle.
The force of the bullet is not equal to the force of the rifle.

Answer:

The mass of the bullet is much greater than the mass of the rifle.

Explanation:

-Emily has a mass greater than the mass of the rifle.

-By Newton's 3rd Law, the gun only moves back in proportion to it's mass.

-This greater mass acts as a shock absorber to the resulting recoil force.

-Due to Emily's greater mass, she'll only experience a force equal to the mass of the bullet which is not enough to make her have the same acceleration as the bullet.
