Figure shows a block of mass m resting on a 20∘ slope. The block has coefficients of friction 0.81 and 0.45 with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass 2.0 kg.
If this minimum mass is nudged ever so slightly, it will start being pulled up the incline. What acceleration will it have?
