Answer to Question #333286 in Mechanics | Relativity for Rose

Question

A certain traveling wave has frequency of 200hz. A wave length of 2m and an amplitude of 0.04m. calculate the displacement (Y) at a point (x) 0,3 from the origin at a time 0.01sec after zero displacement at that point (note, the wave is traveling in opposite direction).

Answer 1

$s(x,t)=-A\cos(2\pi\nu t-\frac{2\pi x}{\lambda}),$

$s(0.3,~0.01)=-0.024~m.$
