This seems like such a pathetically elementary problem, and I feel like a total moron right now. Well, here it is:(adsbygoogle = window.adsbygoogle || []).push({});

When a 58 gram tennis ball is served, it accelerates from rest to a speed of 45 m/s. The impact of the racket gives the ball a constant acceleration over a distance of 44 cm. What is the magnitude of the net force acting on the ball?

The answer is 130 N. The only force formula I know is f=ma. I know that the distance (44 cm) is supposed to be used, and maybe gravity (9.8 m/s^{2}) should be considered but I have no clue how. Thanks for any help :(
