To determine the net force acting on the car, you subtract the force of air resistance from the forward force provided by the engine.
The forward force from the engine is 2000 N, and the backward force of air resistance is 800 N.
Net force = Forward force - Backward force Net force = 2000 N - 800 N = 1200 N
Since the forward force is greater than the backward force, the car will move forward.
Therefore, the car will move with a force of 1200 N forward.
