A block of mass m1 sits on top of a larger block of mass2 which sits on a flat surface. The coefficient of kinetic friction between the upper and the lower blocks is u1, and that between the lower block and the flat surface is u2. A horizontal force F pushes against the upper block, causing it to slide; the friciton force between the blocks then cause the lower block to slide also. Find the acceleration of the upper block...
