I am having difficulties understanding what situation would give a ball a larger velocity. The first situation is a ball is floating infront of you and you hit it with your baseball bat with a given force, and direction. The second situation is that the same ball is coming towards you horizontally ( it already has a non zero velocity) and you hit it with the same magnitude for force and the same direction. I am having difficulites understanding which ball would have a higher velocity, and travel the farthest after being hit. I am thinking its the one that is coming to me horizontally with an intial velocity because the Fnet would be bigger since the baseball bat contributes to the force on the ball plus the reaction force of the bat to the action force of the ball on the bat... It does have to do with Newtons laws doesn't it?
