Suppose you observed the equation for a traveling wave to be y(x,) = cos(x − ), where its amplitude of oscillations was 0. 15 m, its wavelength was two meters, and the period was 2/15 . If a point on the wave at a specific time has a displacement of 0. 12 m, what is the transverse speed of that point?.
