Question

a car is driving down the road when it stikes a ball that was initially stationary in the road. how do the forces compare fot the ball and the car ? how does the accelerstion compare for the ball and the car

Answer 1

According to Newton's third law, equal and opposite forces acts on the ball and car for very small period of time. And impulse acceleration acts on ball in forward direction in the direction of mutual internal reaction force and on the car in backward direction in which mutual internal reaction force. Though internal force is equal but acceleration magnitude depends on the masses of ball and car.
