Ok this problem does have me stumped. This is the area in the chapter I am a little sketchy on. So here is the prob.(adsbygoogle = window.adsbygoogle || []).push({});

A .5kg mass at the end of a spring vibrates at 3hz, with an amplitude of .15m. What is the velocity when it passes through the equalibrium point.

So I figured that this is an energy situation where E=1/2mv^2. But do I know the energy? Also where does the frequency come in?

Thanks again

Chris
