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.
