Решение задачи по физике раздел 29 пункт 77 механика

77. The two lead balls mass m1 = 2 kg and m2 = 3 kg suspended on strings of length l = 70 cm. The original balls touch each other, then a smaller ball bent at an angle α = 60 ° and released (see. Figure). Considering hit central and inelastic, determine: 1) the height h, which rise after hitting balls; 2) energy? T expended on the deformation of the balls when struck.
