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.

To find the magnitude of the net force acting on the soccer ball, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.

In this case, the mass of the soccer ball is given as 0.37 kg. The acceleration of the soccer ball has both horizontal and vertical components, which are given as 830 m/s^2 and 1100 m/s^2, respectively.

To find the magnitude of the net force, we need to find the total acceleration of the ball. We can use the Pythagorean theorem to find the resultant acceleration:

Total acceleration = √(horizontal acceleration)^2 + (vertical acceleration)^2

Plugging in the values, we have:

Total acceleration = √(830 m/s^2)^2 + (1100 m/s^2)^2

Simplifying, we get:

Total acceleration = √(688900 m^2/s^4 + 1210000 m^2/s^4)

Total acceleration ≈ √1898900 m^2/s^4

Total acceleration ≈ 1378.02 m/s^2

Now, we can find the net force by multiplying the mass of the ball by the total acceleration:

Net force = mass × total acceleration

Net force = 0.37 kg × 1378.02 m/s^2

Net force ≈ 509.21 N

Therefore, the magnitude of the net force acting on the soccer ball at this instant is approximately 509.21 N.
