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

The equation of a wave along the x-axis is given as: ξ cm = 4.9 sin (1.06 x - 0.77 t)

in which ξ is the displacement. Units on the right hand side are 1/cm for К and 1/s for ω.

Determine the the traveling speed of the wave.

Express the result in the unit m/s and to three significant figures. If you must use scientific notation, please enter as follows: e.g. 0.000123 = 1.23E-4. Only answer in numerical values, no units. For negative numbers, leave no space between the negative sign and the number: e.g. right: -1.00, wrong: - 1.00.

2. Relevant equations

I would think V= w/k

3. The attempt at a solution

V = 0.77/1.06

= 0.726

This is the wrong answer
