Three identical bricks are pushed across a table at constant speed as shown below. The hand pushes horizontally. (Note: There is friction between the bricks and the table.) Call the stack of two bricks system A and the single brick system B. A Constant Speed Make complete and properly labeled force diagrams for each system. Identify all third-law force pairs on your force diagrams by placing one or more small "x" symbols through each member of the pair. For example, if you have two sets of third-law force pairs shown on your diagrams. mark each member of the rst pair asHh, and each member of the second pair as-'HH'. Also provide a ranking of all horizontal forces that appear in yourdiagrams. Three identical bricks are pushed across a table with the same force as in the previous discussion. The hand pushes horizontally. (Note: There is friction between the bricks and the table, but it is weaker than it was in the previous discussion). Call the stack of two bricks system A and the single brick system B, as we did previously. Also, let system C represent the system consisting of all three bricks ' System C _____ '1 Compare the magnitude of the net force on system C to the magnitudes of the net forces on systems A and B. Explain your conclusions. Make a complete and properly labeled force diagram for system C. Do the forces between system A and B appear in your diagram? Explain why or why not
