Question

A wave travels along a taut string in the positive x-axis direction. Its wavelength is 40 cm and its speed of propagation through the string 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 oscillation amplitude, y = + A.
a) Write the equation of the wave in the form of sine [y = A sin (kx ± ωt + φ)], numerically identifying each parameter.
b) What oscillation speed on the y axis does the point of the chord have 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?
