Waves on a string are described by the following general
quation
y(x,t) = A cos(kx - wt).
A transverse wave on a string is traveling in the + direction with
a wave speed of 9.00 m/s, an amplitude of 9.00x10-2 m, and
a wavelength of 0.550 m. At time t = 0, the x=0 end of the
string has its maximum upward displacement. Find the transverse
displacement y of a particle at x = 1.63 m and t = 0.150 s.
Note that if y = A at a given 2 and t, then the position z represents a point of maximum displacement at the time specified.
