Answer:
3 N to the right
Step-by-step explanation:
There are two forces acting on the car:
- A force of 10 N towards the right
- A force of 7 N towards the left
Therefore, the net force is given by the difference between the two, since they are in opposite directions:
![F=10 N-7 N=3 N](https://img.qammunity.org/2019/formulas/physics/high-school/yilsg98umozuvfrq5hmnobl0mb044u7dku.png)
And the direction is to the right, since the force to the right has greater magnitude than the force to the left.
