a car reaches the speed limit, and the driver engages cruise control, keeping the car at a constant speed. provided the driver remains on cruise control and drives in a straight line, which statements are correct about the cars motion?
□ there is no net force acting on the car.
□ there are no forces acting on the car.
□ the car is still accelerating forward.
□ the car has stopped moving.
□ the car is no longer accelerating.
□ the air resistance force is equal in magnitude to the forward force of the ground on the car.

Explanation:

1. For constant straight-line speed, Newton's first law states net force is zero (balanced forces, not no forces).
2. No acceleration means no change in speed/direction, so the car is not accelerating.
3. Balanced forces mean air resistance equals the forward ground force on the car.
4. The car moves at constant speed, so it is not stopped nor accelerating forward.

Answer:

• There is no net force acting on the car.
• The car is no longer accelerating.
• The air resistance force is equal in magnitude to the forward force of the ground on the car.
