a set of function attached to the bottom of a box which is then measured and found have a mass6kg the box is placed on the floor and student of the physics used a brief horizontal force of 150 newton to push the-box sideway-after which the roll ac cross the floor with the constant volicity how much doesworks the floordo on the boxas its rolls along
If the box rolls on a horizontal floor with a constant velocity, then it is in dynamic equilibrium, and no external (horizontal) force is acting on it. Thus the floor does zero work on the box.
