B. 10,400 N D. 399 N. C___ 2. If a car is moving to the left with constant velocity, one can conclude that. A. there must be no forces applied to the car. B. the net force applied to the car is directed to the left. C. the net force applied to the car is zero. D. there is exactly one force applied to the car. A___ 3.
The first law states that an object will stay at rest or at constant velocity until a force acts on it. The second law states that the acceleration of a body is equal to the force acting on the body divided by its mass. If no force acts on a body it will have no acceleration and hence either remain at rest or remain at a constant velocity.
