    Waves and Sound Vibrations Question Urgent Please Help!?!?

    1. The problem statement, all variables and given/known data
    A mass suspended from the end of a spring vibrates up and down 25 times in 50s. What ar ethe frequency and period of the vibration.


    2. Relevant equations
    F = 1/T
    T = 2(pie)3.14(squrroot)L/g


    3. The attempt at a solution
    F = 1/T
    or is it:
    F = 50/25
    F = 2Hz???

    T = 2(3.14)(sqrroot) but what is the L????

    I'm very confused and I need to finish this soon!:confused::frown::cry:

    Frequency = number of vibrations per second.
    Period T = time for one vibration = 1/f
