Задача id12636

A block of mass M = 2 kg lies on a smooth horizontal table, on which there is a block of mass m = 1 kg. Both bars are connected by a light thread thrown over a weightless block (Fig. 24). What force F must be applied to the lower block so that it begins to move away from the block with constant acceleration a = g/2? The coefficient of friction between the bars is k = 0.5. Neglect the friction between the bottom block and the table.
