Answer:
Unbalanced, then balanced OR only unbalanced
Step-by-step explanation:
At first, the force is unbalanced. This is what is causing the car to move. Then, the car slows down. If the car were to stop, then it would be unbalanced, then balanced. However, if the car never stops, then it would stay unbalanced the whole time. While it is not a specific answer, I hope this helps!
