A bullet of mass 50 g moving horizontally with a velocity 210 ms^(-1) gets embedded in a block of mass 1 kg kept on a rough horizontal surface. If the coefficient of kinetic friction between the block and surface is 0.5. The block- bullet system will move a distance of "______" before coming to res t(Acceleration due to gravity =10 ms^(-2)).

A block of mass m_(2) is placed on a horizontal table and another block of mass m_(1) is placed on top is it. An increasing horizontal force F = alpha t is exerted on the upper block but the lowwer block never moves as a result. If the coefficient of friction between the blocks is mu_(1) coefficient of friction between the blocks is mu_(1) and that between the lower block and the table is mu_(2), then what is the maximum possible value of mu_(1)//mu_(2) ?
