Block m1 sits at rest on the surface of an inclined plane with angle = 35. It is connected to another block (m2 = 7.0 kg) by a light rope and a massless/frictionless pulley. The surface of the plane is frictionless, but the coefficient of static friction between the blocks is s = 0.24. What is the largest value of m1 for which the blocks remain motionless? For the representation, draw a free-body diagram for each block. (Hint: drawing the free-body diagrams is critical for solving this problem.) For the limits check, investigate what happens to m1 as friction between the blocks becomes negligible (i.e., as s 0).
