Здравствуйте! У меня возникли сложности с таким вопросом:
3. Дифференциальное уравнение затухающих колебаний имеет вид: 0,5d^2x/dt^2+0,25dx/dt+8x=0. Определить коэффициент затухания и круговую частоту этих колебаний.

Здравствуйте, dar777!
Согласно формулам на с. 135 [1], в Вашем случае
Тогда коэффициент затухания
(с-1);
циклическая (круговая) частота свободных колебаний в отсутствие трения
(с-1);
собственная циклическая частота колебаний
(с-1).
