Столкновение шариков. Два небольших шарика массами 22m и 3m покоятся на гладкой горизонтальной поверхности на расстоянии L=3 м друг от друга. Их центры находятся на одной горизонтальной прямой. По направлению к более тяжёлому шарику вдоль этой прямой со скоростью V=120 м/с летит пуля массой mm. Пробив насквозь этот шарик, пуля летит дальше со скоростью V/12, попадает в более лёгкий шарик и застревает в нём. Через какое время после попадания пули в более тяжёлый шарик шарики столкнутся друг с другом? Ответ выразить в сс, округлив до десятых. Время взаимодействия шариков с пулей считать очень малым. Размерами шариков пренебречь. Изменение скорости пули при движении между шариками не учитывать.
