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

The drawing shows a snapshot of a transverse wave traveling along a string at 8.8 m/s. The equation for the wave is y(x, t) = A cos (wt + kx).

(a) Is the wave moving to the right or to the left?

To the left

(b) What are the numerical values of A, w, and k?

A 2 mm,

w rad/s

k rad/m

(c) At what times could this snapshot have been taken? (Give the three smallest nonnegative possibilities in order.)

ms ms ms

2. Relevant equations

Kx=n * pi

3. The attempt at a solutionI found the amplitude to be 2mm but I am not really sure where to go from their. I tried solving for w with the velocity but it doesn't give you frequency or wave length. Please help I am lost!

Sorry I just attached a picture of the graph
