Transverse waves on a string have wave speed 8.00 m/s, amplitude
0.0700 m, and wavelength 0.320 m. These waves travel in the x
direction, and at t = 0 the x = 0 end of the string is at y = 0 and
moving downward. Find the transverse displacement of a point on the
string at x_2 = 0.280 m at time t_2 =
0.130 s .
