Learning goal: to practice problem-solving strategy 15.1 mechanical waves. waves on a string are described by the following general equation y(x, t)=acos(kx−ωt). a transverse wave on a string is traveling in the +x direction with a wave speed of 9.00 m/s , an amplitude of 9.00×10−2 m , and a wavelength of 0.480 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 = 1.59 m and t = 0.150 s .
