The car's velocity is forward, and its acceleration is forward. B. The car's velocity is backward, and its acceleration is forward. C. The car's velocity is backward, and its acceleration is backward. D. The car's velocity is forward, and its acceleration is backward. - Answer - D. The car's velocity is forward, and its acceleration is backward. A car moves forward along a horizontal road in a straight line at constant speed. The net force on the car is _______. - Answer - zero You are pushing a file cabinet across a floor in a straight line at a constant speed. Which of the following can you correctly conclude about the forces acting on the file cabinet? A, If you were to exert twice as much force on the file cabinet, it would slide across the floor at twice its original speed. B. The force that you are exerting on the file cabinet is greater than the force that friction is exerting on it. C. The force that you are exerting on the file cabinet is greater than the force of friction with the cabinet's weight. D. The force that you are exerting on the file cabinet is equal and opposite to the force that friction is exerting on it. - Answer - D. The force that you are exerting on the file cabinet is equal and opposite to the force that friction is exerting on it.
