In the following system: mi F m2 a pair of stacked blocks attached via a string looped around a pulley (on left) is acting on by an applied force, F, pulling the bottom block. There is friction between all contact surfaces. Using your Free Body Diagrams from the previous two questions, deriven expression the minimum Force, F to get the system moving, check the expression for units and limiting behaviour and obtain a value for F, if m1 = 3 kg, m2 = 6.2 kg and the coefficient of static friction is j = 0.2.
