Задача id12687

Two elastic balls are suspended on thin threads side by side so that they are at the same height and touch. The suspension threads are of different lengths: l1 = 10 cm, l2 = 6 cm. The masses of the balls are m1 = 8 g and m2 = 20 g, respectively. A ball with mass m1 is deflected through an angle a = 80° and released. Determine the maximum deviation of the balls from the vertical after the impact. The impact is considered to be absolutely elastic.
