Final answer:
When all other forces on the car are balanced, there is no net force on the car, which means the car is at rest or moving at a constant velocity.
Step-by-step explanation:
When all other forces on the car are balanced, the statement that describes the forces on the car is option A. There is no net force on the car. According to Newton's first law, an object at rest or moving at a constant velocity has a net force of zero. In this case, since all other forces are balanced, there is no acceleration or deceleration, and the car is either at rest or moving at a constant velocity.
