Finding a period of a pendulum

  1. Mar 5, 2013 #1
    1. The problem statement, all variables and given/known data
    Find the period of a pendulum with a length of 35 cm.


    2. Relevant equations
    I know that you can find period with the equation my teacher gave me: T(period in sec)=1/f(frequency in hertz) but that doesn't have anything to do with cm. I'm clueless on what equation to use?


    3. The attempt at a solution
    I know I need to get 35cm to m so that's .35m. now i am stuck.

    If someone could just give me a guideline and explain a little that would be nice. I don't exactly want an answer. I need to try that on my own.

    Thank you!
