Need the answer for part b

Part A (Figure 1) shows a block of mass m resting on a 20 slope. The block has coefficients of friction /s = 0.76 and uk = 0.55 with the surface. It is connected via a massless string over a massless, frictionless pulley to a What is the minimum mass m that will stick and not slip? hanging block of mass 2.0 kg.
