Homework Statement
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
Homework Equations
Kx=n * pi
The Attempt at a Solution
I 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
