Homework Statement


If the initial period is 3.0 s and the mass is reduced to 1/3 of its initial value, what is the new period?


Homework Equations



Possibly T=2pi*squareroot(m/k)


The Attempt at a Solution


The solution is something close to 1.73. I have no idea what equation to use, even. Any assistance would be appreciated.

You have the right equation, just use it. 3s=T=2pi*sqrt(m/k). Now change m->m/3. By what factor does T change?
