Homework Help: Simple pendulum problem - confirmation

  1. Nov 24, 2005 #1
    Hi, I got this question:
    Ok, for the period:

    [tex]\frac{180\textit{s}}{72.0} = 2.50{\textit{s}}[/tex]

    Then I found the pendulum equation that I don't understand well. I arraganged it to find the gravity:

    [tex]g = \left( \frac{2\pi\sqrt{\ell}}{T} \right) ^2 [/tex]

    Then I plugged in the numbers and got the answer. Did I do this correctly? :confused:
