Answer:
200 N.
Step-by-step explanation:
Hello,
In this case, since the ball with a defined mass is moving at 15 m/s and the bat with a greater mass moves at 20 m/s, by recalling the newton's third law, we can infer that even when they have different velocities and masses, in order to successfully hit the ball with the bat, they must do the same force, that is 200 N.
Best regards.
