To find the net force acting on the car, we need to consider both the forward force provided by the engine and the opposing force of air resistance.
Given:
- Forward force (engine) = 2000 N
- Air resistance (opposing force) = 800 N
The net force can be calculated as follows:
\[ \text{Net Force} = \text{Forward Force} - \text{Air Resistance} \] \[ \text{Net Force} = 2000 , \text{N} - 800 , \text{N} = 1200 , \text{N} \]
The net force is 1200 N in the forward direction (the same direction as the engine's force).
Therefore, the car will move forward with a net force of 1200 N.
