Homework Help: Damped Oscillatory motion : Period

  1. Mar 31, 2015 #1

    Relevant equations

    1) upload_2015-4-1_0-16-27.png
    2) [tex] T = \sqrt{ \frac{m}{k} } [/tex]
    3) [tex] T = \frac{2 \pi }{ \omega } [/tex]

    In some problems about damped oscillatory motion, the requests ask for example "Calculate the amplitude after 20 oscillations"

    I know that i need to find the period first of all but :

    Do i find the period by using equation number 2? Is that constant? I've seen other threads where they calculated T with (2) and used it for everything but, if we have a different value of \omega overtime, why did we use the initial \omega to find the period?

    If i divide 2π by

    what do I find? Isn't that the period?
