Здравствуйте! У меня возникли сложности с таким вопросом:
На однородный цилиндрический блок массой m_2 и радиусом R намотана невесомая нить, к свободному концу которой прикреплен груз массой m_1. К блоку крестообразно прикреплены четыре одинаковых невесомых стержня, на которых закреплены одинаковые грузы массой m_3 на расстоянии от оси вращения. Грузы m_3 можно считать материальными точками. Трением в блоке можно пренебречь. Найти зависимость ускорения a груза m_1 от расстояния x. Построить график этой зависимости в интервале изменения x от R до 3R. Ускорение свободного падения g=9,81 (м )/с^2 . Огромное спасибо
