At an instant when a soccer ball is in contact with the foot of a player kicking it, the horizontal or x component of the ball's acceleration is 810m/s^2 and the vertical or y component of its acceleration is 110m/s^2. The ball's mass is 0.43kg. what is the magnitude of the net force acting on the soccer boll at this instant?

X = 810 m/s^2.
Y = 110 m/s^2.

a = sqrt(X^2 + Y^2),
a = sqrt(656100+12100) = 814 m/s^2.

Fn = ma = 0.43 * 814 = 350 N.=Net force.
