Two loads with masses m1 = 10 kg and m2 = 15 kg are suspended on threads of length l = 2 m so that they are in contact with each other. The smaller load was deflected by 60° and released. To what height will both weights rise after the impact? The impact is considered inelastic.

A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
