Question

2-A wave travels a taut string in the positive direction of the x axis. Its wavelength is
40 cm and its speed of propagation by the rope is 80 m / s. The amplitude of the wave is
0.60 cm. At t = 0 the point of the chord at x = 0 is at the point of maximum amplitude of
oscillation, y = + A.
a) Write the equation of the wave in the form of sine [y = A sin (kx ± ωt + φ)], identifying
numerically each parameter.
b) What oscillation speed on the y axis has the point of the chord at x = 0 at time t =
0.0010 s?
c) If the linear density of the rope is 12 g / m, what is the tension in the rope?
