During a baseball game, a hitter strikes the ball with a bat. When this happens, the ball and the bat exert a force on each other. Why does the ball accelerate away from the bat more than the bat accelerates away from the ball?
The ball has less mass, so it exerts less force on the bat.
The ball has greater velocity before the collision, so the force affects the ball more than it affects the bat.
The bat exerts more force than the ball because the batter is exerting a force on the bat as it hits the ball.
The ball has less mass, so the equal force on the ball and the bat causes greater acceleration of the ball.
