Find Maximum Transverse velocity of string

[aseylys]

Homework Statement

For a string of length 100m with fixed ends, a pulse is traveling to the right at a speed of 40 m/sec. The pulse has a wavelength of 2 meters and an amplitude of .1 m.

Homework Equations

y=A*Sin(kx-wt) ((where w is omega))
$\lambda$=2*pi/k
frequency=w/2pi
Velocity=w/f
Velocity=f/$\lambda$
V_max=w*A

The Attempt at a Solution

So I plugged in as much as I could:
y=A*Sin(kx-wt)
$\lambda$=2 so 2=2pi/k ==> k=pi (?)

I can't figure out how to get w (omega). So I'm kinda stuck at a dead end. Anyone have any suggestions?
