To determine the net force on the car, we can subtract the force of air resistance from the engine's forward force:
\[ \text{Net Force} = \text{Forward Force} - \text{Air Resistance} = 2000 , \text{N} - 800 , \text{N} = 1200 , \text{N} \]
Since the forward force is greater than the air resistance, the net force is in the forward direction.
Therefore, the car will move with a force of 1200 N forward.
