    A block A with a mass of 3 kg rests on a horizontal table top. The coefficient of kinetic friction, μk = 0.5. A horizontal string is attached to A and passes over a massless, frictionless pulley, and block B with mass 2 kg hangs from it. Because of the pull of gravity, the masses accelerate. What is the Tension in the string (in Newtons)?

    Block B, with mass 5.00 kg, rests on block A, with mass 8.00kg. There is no friction between the table and block A, but the coefficient of static friction between block A and B is 0.750. A "massless" string attached to block A passes over a frictionless pulley and block C is suspended from the other end of the string. If we want ALL the blocks moving together with the same acceleration, the largest possible mass that block C can...
