A system consists of three masses m,, m, and me
connected by a string passing over a pulley P. The
mass m, hangs freely and m, and m, are on a rough horizontal table (The coefficient of friction= u). The pulley is frictionless and of negligible
mass. The downward acceleration of mass m, is:
(Assume m = m = m2 = m)
