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 860 m/s2 and the vertical or y component of its acceleration is 930 m/s2. The ball's mass is 0.38 kg. What is the magnitude of the net force acting on the soccer ball at this instant?
Multiply acceleration by mass for the force components in horizontal and vertical directions:
Up: 930/0.38 = 2447 N
Horizontal: 2263 N
Magnitude: sqrt[(2447^2 + 2263^2] = 3333 N
