Three identical bricks are pushed across a table at constant speed as shown below. The hand pushes horizontally. (Note: There is friction between the A Constant speed B bricks and the table.) Call the stack of two bricks system A and the single brick system B. 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 first pair as->, and each member of the second pair as->. Also provide a ranking of all horizontal forces that appear in your diagrams
