Здравствуйте! У меня возникли сложности с таким вопросом:
Грузик на пружинке совершает вынужденные вертикальные затухающие колебания в вязкой жидкости под действием внешней силой, меняющейся со временем по гармоническому закону: Fx(t)=F0 cos(wt ). Оказывается, что амплитуда смещения грузика из положения равновесия максимальна при частоте w=b, а амплитуда скорости грузика максимальна при частоте w=a , причем a=3b . Рассчитайте на основании этих данных величину коэффициента затухания собственных колебаний такого пружинного маятника в данной жидкости
