Задача №32.60
Условие
Под действием силы сопротивления R, пропорциональной первой степени скорости (R=αv), тело массы m, подвешенное к пружине жесткости c, совершает затухающие колебания. Определить, во сколько раз период затухающих колебаний T превосходит период незатухающих колебаний T0, если отношение n/k=0,1 (k2=c/m, n=α/(2m)).Решение
