A system has three masses, a 10kg mass is lying on a level surface and is connected on the left to a 6kg mass by a cord passing over a massless,frictionless pulley.And on the right, it is connected to a 9kg mass by a cord also passing over a frictionless,massless pulley. The coefficient of kinetic friction on the 10 kg mass is 0.20.what is the acceralation of the system and the tensions in the left and right cord?
