M = unit mass of 1 kg is mounted on the end of the section. Giri 1 and 2 equal masses m1 = m2 = 1 kg connected thread thrown through the block. Kettlebell 2 is on the surface of the table, the weight 1 is suspended from the table. Coefficient of friction on the table weights 2 k = 0,1. Find the acceleration with which the moving weights, and the tensile force of filaments T1 and T2. Block considered uniform drive. Friction block neglected.
