OpenStudy (sjg13e):
Question: M1 has a mass of 5.250 kg. It is on a horizontal surface, connected by a massless string to a hook where mass M2 can be increased smoothly. The pulley has a negligible mass and no friction. When M2 = 7.88kg it begins to accelerate downwards at a rate of 1.833 m/s^2. Calculate us (static friction) - uk (kinetic friction) between M1 and the surface.
