The vertical displacement of an ocean wave is described by the function, y = A sin(ωt - kx). k is called the wave number (k = 2π/λ) and has a value of k = 18 rad/m. The remaining values are A = 9.5 m and ω = 14.5 rad/s.
a) Using y = A sin(B), input an expression for B where the wave would be traveling in the -x-direction. sig. gif?tid=7M79-31-9F-4E-8624-20536
b) What is the wave's velocity in m/s?
c) What is the wave's amplitude in m?
