## Homework Statement

If y(x,t)=(6.0mm)sin(kx+(600rad/s)t+[tex]\Phi[/tex]) describes a wave traveling along a string, how much time does any given point on the string take to move between displacements y= +2.0mm and y= -2.0mm?

## Homework Equations

I think y(t)=ym sin([tex]\omega[/tex]t) ?

## The Attempt at a Solution

well if I plug in 2.0mm for y, 6.00mm for ym and 600rad/s for [tex]\omega[/tex] I come up with the equation 2.0mm=6.00mm sin (600rad/s * t). Where do I go from here? are my assumptions correct so far?

Other things as I am thinking- 600rad/s is about 95.5Hz so each complete cycle from +6mm to -6mm should take .01s or so, so my answer should be less then that.

Thanks for your help
