By applying a constant horizontal force of magnitude F, a student pushes a heavy box of mass M along the kitchen floor at a constant speed v. The coefficient of kinetic friction between the floor and the box is μK. now the student doubles the size of the applied force, so the magnitude of the constant horizontal force which he applies is 2F. What can you say about the motion of the box while the force 2F is being applied? A) The box has a constant acceleration of magnitude F/M  B) The box has a constant acceleration of magnitude 2F/M C) The box has a constant speed of 2v D) The box has a constant acceleration of magnitude between F/M and 2F/M
