Vibrations and Waves - please help

    Vibrations and Waves - please help!!

    I'm having trouble with my physics homework. I can't seem to figure out which formula to use to solve a particular problem.

    "If a particle undergoes SHM with amplitude 0.25m, what is the total distance it travels in one period?"

    The formulas I have that deal with amplitude are:
    [tex]V[/tex]= [tex]\pm[/tex][tex]V{o}[/tex][tex]\sqrt{1 - x^{2}/A^{2}}[/tex]


    x=[tex]Acos2[/tex]* [tex]\pi[/tex](frequency)t​

    I don't know which formula to use because it seems like I don't have enough information for any of them. Could someone please tell me which formula to use and why?

    so r=sqrt(A/4pi)

    your A=0.25
