## Homework Statement

You are told that, at the known positions x[itex]_{1}[/itex] and x[itex]_{2}[/itex], an oscillating mass m has speed v[itex]_{1}[/itex] and v[itex]_{2}[/itex]. What are the amplitude and angular frequency of the oscillations?

## Homework Equations

x(t) = Acos(wt - [itex]\delta[/itex])

v(t) = -Awsin(wt -[itex]\delta[/itex])

w = [itex]\sqrt{\frac{k}{m}}[/itex]

probably others?

## The Attempt at a Solution

I need help solving this. I know what the answer should be but I'm not sure if these are the equations I should be using. And if they are, I'm not really sure how to start it. I wrote out all the equations and have just sort of been staring at them. Can someone just help get me started?
