**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]

[tex]V[/tex]=[tex]A\sqrt{k/m}[/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 [tex]V[/tex]=[tex]A\sqrt{k/m}[/tex]

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

**why**?
