To determine the net force acting on the car, you subtract the force of air resistance from the forward force provided by the engine.
Given:
- Forward force (engine) = 2000 N
- Backward force (air resistance) = 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 in the forward direction.
Thus, the correct answer is: 1200 N forward.
