1. The problem statement, all variables and given/known data For a string of lenght 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. 2. Relevant equations y=A*Sin(kx-wt) ((where w is omega)) [itex]\lambda[/itex]=2*pi/k frequency=w/2pi Velocity=w/f Velocity=f/[itex]\lambda[/itex] V_max=w*A 3. The attempt at a solution So I plugged in as much as I could: y=A*Sin(kx-wt) [itex]\lambda[/itex]=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?
