Worksheets due Dec 15, 2022 10:00 PST Completed WQ6.3 4/4 points (graded) We will now consider all three blocks as one system, so system C consists of all three blocks. The motion of the blocks is the same as in question WQ6.2 on the previous page. Hand System C a) How does the magnitude of the net force on system C relate to the magnitude of the net forces on system A and system B? OFnet, A = Fret, C and Fnet, B = Fnet, A OFnet, A = Fret, C and Fret, B = \ Fnet, C OFnet, A =Free, C and Enet, B =\Fnet, Fret, A = Fres, C and Fret, B = {Fnet, C O Fret, A ={Fres, C and Fret, B = \Fnes, C V b) On a piece of paper, draw and label a free-body diagram for system C. Enter 'yes' below when complete. yes V c) Compare the forces that appear on your free-body digram for system C to those that appear on your digrams for systems A and B. Which of the following forces did you draw for systems A and B that you did not draw for system C? O Ffriction FA on B Frand All previous forces also appeared in this diagram. d) Why is it not necessary to consider these forces in determining the motion of system C? Note that such forces are sometimes called internal forces, to be distinguished from external forces. They are always zero C They are very small O It would make the diagram too hard to read They always cancel eachother out in the net force.
