Box 1 and Box 2 sit at rest on a surface as shown in the diagram, until a constant force F- is applied to Box 1. After the force is applied, the boxes move to the right at a constant speed, v. The mass of Box 2 is twice the mass of Box 1.
1. Draw two free body diagrams, one for each box.
2. Consider all of the horizontal forces from your free body diagrams. Rank the magnitudes of these forces from greatest to least. If any forces are equal, state so explicitly. Provide justification for your ranking. If any forces cannot be included in your ranking, state so explicitly and explain why the situation prevents you from including them.

As shown in the diagram, the 15-kg box B moves to the right at an initial velocity vo = 2 m/s when d = 0.7 m. A force F = 120 N along a specified direction is applied on the box during the entire motion of the box along a smooth floor.
