Wave function is expressed as:

$\overline{){\mathbf{y}}{\mathbf{\left(}}{\mathbf{x}}{\mathbf{,}}{\mathbf{t}}{\mathbf{\right)}}{\mathbf{=}}{\mathbf{A}}{\mathbf{s}}{\mathbf{i}}{\mathbf{n}}{\mathbf{\left(}}{\mathbf{\omega }}{\mathbf{t}}{\mathbf{-}}{\mathbf{k}}{\mathbf{x}}{\mathbf{+}}{\mathbf{\varphi }}{\mathbf{\right)}}}$

(a)

Speed of a wave is:

v = ω/k = 14π/2π = 7 m/s and is in positive x-direction.

The speed and direction of travel of the wave is  7 m/s in the positive x-direction.
