(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A continuous succession of sinusoidal wave pulses are produced at one end of a very long string and travel along the length of the string. The wave has frequency 36.0Hz, amplitude 5.50mm, and wavelength 0.635m.

a) How long does it take the wave to travel a distance of 8.50m along the length of the string?

b) How long does it take a point on the string to travel a total accumulated transverse distance of 8.50m, once the wave train has reached the point and set it into motion?

2. Relevant equations

So I've been able to do part a) with ease but the trouble I'm having is with part b). It just completely confuses me!

Do I need to use the equation [itex]y(x,t) = Acos(kx - \omega t)[/itex] or [itex]\frac{\partial^{2}y(x,t)}{\partial x ^{2}} = \frac{1}{v^{2}} \frac{\partial ^{2}y(x,t)}{\partial t^{2}}[/itex] or [itex]v_{y}(x,t) = \omega Asin(kx - \omega t)[/itex] or something different??

3. The attempt at a solution

So for part a) I got t=0.372 seconds using [itex]v=f\lambda[/itex] and b) is an unknown to me.

Thanks in advance if anyone can help!
