At an instant when a soccer ball is in contact with the foot of the player kicking it, the horizontal or x component of the ball's acceleration is 930 m/s2 and the vertical or y component of its acceleration is 930 m/s2. The ball's mass is 0.39 kg. What is the magnitude of the net force acting on the soccer ball at this instant?

F = ma

= 0.39 * 930√2
