Question

a car is moving in a straight line at a constant velocity. which statement best predicts the cars continued motion?
the car will come to a complete stop when the slowing forces are less than the forces propelling it forward.
the car will begin to move right or left at a new velocity because there are no new changes in the forces that continue to act on the car.
the car will begin to speed up when the slowing forces are greater than the forces propelling it forward.
the car will continue to move in a straight line at the same velocity as long as the same forces continue to act on the car.

Explanation:

According to Newton's first - law of motion, an object in motion with a constant velocity will remain in that state of motion unless acted upon by an unbalanced force. When the same forces continue to act on the car, there is no unbalanced force to change its motion.

Answer:

The car will continue to move in a straight line at the same velocity as long as the same forces continue to act on the car.
