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 830 m/s2 and the vertical or y component of its acceleration is 1100 m/s2. The ball's mass is 0.37 kg. What is the magnitude of the net force acting on the soccer ball at this instant?

a = sqrt((830)^2 + (1100)^2 = 1378m/s^2

Fn = ma = 0.37 * 1378 = 510N.
