2. Two masses are attached to a string that passes over a pulley. The mass of block I is greater than the mass of block 2 (mi> m2). While mass 2 slides up against a wall it experiences a known force of friction (FF) between it and the wall resisting the block's motion as it accelerates up the wall. a. (SEP4 - Graphs) In the space below the diagram, draw separate FBDs for my and mz. The size of forces should be relative and comparable across both diagrams. Indicate MI any forces that are equal. If a force is larger than another force, the arrow should be clearly longer (or make a note stating this). b. (SEP5 - Math) Derive an equation for the acceleration (a) of mass 2 in terms of my, m2, friction force (FF) and other physics constants as needed. Show your work
