Two blocks A and B of mass 10 kg and 15 kg are connected with a massless string that runs on frictionless pulley. Block A moves along a plane that make an angle of 45o with the horizontal. The block B moves downward with constant velocity. Find the magnitude of friction and coefficient of kinetic friction.
