Snapshot Graph of String Displacement at Time Instant

[admartin]

A snapshot graph??

Homework Statement

The figure(Figure 1, see URL) is a snapshot graph of the instantaneous velocity of the particles on a string. The wave is moving to the left at 50 m/s.

Draw a snapshot graph of the string's displacement at this instant of time.

Homework Equations

D(x,t)=Asin(k*x+omega*t+initial phase)

The Attempt at a Solution

I honestly don't even know where to start. I am so confused. Please help!

A snapshot graph of the string's displacement would be a graph showing the displacement of each particle on the string at a given instant of time. To draw this graph, you would need to know the amplitude, wave number, angular frequency, and initial phase of the wave. You could then use the equation D(x,t)=Asin(k*x+omega*t+initial phase) to calculate the displacement for each x-coordinate at the given time. Then, you could plot the points and connect them to form the graph.
