A system consists of three identical masses m1,m2 and m3 connected by a string passing over a pulley

A system consists of three identical masses m1, m1, m1, m2 and m3 connected by a string passing over a pulley P. The mass m1 hangs freely and m2 and m3 are on a rough horizontal table (the coefficient of friction=mu) The pulley is frictionless and of negligible mass. The downward acceleration of m1 is (Assume m1=m2=m3=m).
