Final answer:
The net force on the car is 52 N.
Step-by-step explanation:
To find the net force acting on a car, we need to subtract the friction force and air resistance force from the forward force exerted by the car. The net force can be calculated using the equation Fnet = Fforward - Ffriction - Fair resistance.
Given that the forward force is 75 N, the friction force is 10 N, and the air resistance force is 13 N, we can plug these values into the equation to get Fnet = 75 N - 10 N - 13 N = 52 N.
Therefore, the net force on the car is 52 N.
