OUTCOME FR4 - only attempt it not mastered on previous exam I can calculate forces in more complex applications FR4: Similar to the set up in your Forces lab, a block of wood is'connected to a mass. The string that ties them together is over a pulley, because the mass is able to fall. The block is on a frictiony surface. This set up is shown in the diagram. If the wooden block has mass of 300 g, the hanging mass is 150 g, and the coefficient of friction between the block and surface is 0.3, find the acceleration of the block- mass system
