Two blocks of masses M_(1)=4 kg and M_(2)=6kg are connected by a string of negligible mass passing over a frictionless pulley as shown in the figure below. The coefficient of friction between the block M_(1) and the horizontal surface is 0.4. when the system is released, the masses M_(1) and M_(2) start accelrating. What additional mass m should be placed over M_(1) so that the masses (M_(1)+m) slide with a uniform speed?
