A system consists of three masses m_1, m_2 and m_3 connected by a string passing over a pulley {\P}. The mass m_1 hangs freely and m_2 and m_3 are on a rough horizontal table (the coefficient of friction =\mu ). The pulley is frictionless and of negligible mass. The downward acceleration of mass m_1 is : (Assume m_1=m_2=m_3=m )
