To determine the net force acting on the car, you need to consider the forward force provided by the engine and the opposing force of air resistance.
- Forward force (engine): 2000 N
- Opposing force (air resistance): 800 N
The net force can be calculated by subtracting the opposing force from the forward force:
\[ \text{Net force} = \text{Forward force} - \text{Opposing force} \]
\[ \text{Net force} = 2000 , \text{N} - 800 , \text{N} = 1200 , \text{N} \]
The car will move in the direction of the net force, which is forward (in the direction of the engine's force).
In summary, the car will move with a net force of 1200 N in the forward direction.
