Rachel is pushing a box across the floor while Jon, at the same time, is hoping to stop the box by pushing in the opposite direction. There is friction between the box and floor but you may ignore the effect of air resistance. Draw the force diagram for the box's motion and then choose the appropriate forces from the following list that should be included on the force diagram. Assume that the box is moving to the right during the...
