A horizontal constant force F pulls a block of mass m placed on a horizontal surface. If the coefficient of kinetic friction between the block and ground is mu , find the power delivered by the external agent after a time agent after a time t measured from the beginning of action of the force.

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) ?
