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/s? . 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/s? ? o the force of the bullet is exerted in the same direction, toward the target. o 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.

Abullet is shot into a block of plastic. the bullet penetrates the block 0.25 m. the mass of the bullet is 11 g. it is traveling with a speed of 475 m/s before it hits the block. (a) use kinematic equations to find the magnitude of the acceleration on the bullet as it is penetrating the block (ignore gravity, and assume that the force on the bullet as it penetrates the block is constant). (b) use newton's second law to find the magnitude of the force exerted on the bullet by the plasti

(a) a runaway train car that has a mass of 14000 kg travels at a speed of 7.5 m/s down a track. compute the time (in seconds) required for a force of 1400 n to bring the car to rest. s (5 attempts remaining) input 1 status (b) a bullet is accelerated (from rest) down the barrel of a gun by hot gases produced in the combustion of gun powder. if the average force exerted on a 0.023 kg bullet to accelerate it is 3700 n, what will be the bullet's speed (in m/s) in a time of 0.002 s
