"This figure is a snapshot graph of the instantaneous velocity of the particles on a string. The wave is moving to the left at 50 cm/s.
Draw a snapshot graph of the string's displacement at this instant of time."
So it seems to be a quite basic question, where it's pretty much just an integration with working out the displacement from the velocity graph.
However I don't know how to account for the 50cm/s, and if it's even relevant at all.
I've tried considering v=λf, v=ω/k, and v=-ωA*cos(kx+ωt+θ) (plus ωt because moving to the left) but have gotten nowhere, especially because I don't know how to work out the phase constant θ, and once again don't know whether it's relevant or not.
Help would be muchly appreciated :)
