Final answer:

The magnitude of the net force required to stop the car is 6720 N.

Step-by-step explanation:

To find the magnitude of the net force required to stop a car, we can use the equation:

F = (m * v^2)/(2 * x)

where F is the force, m is the mass of the car, v is the initial velocity, and x is the stopping distance. Plugging in the given values:

F = (1050 kg * (40.0 km/h)^2) / (2 * 25.0 m) = 6720 N
