Q- An apparatus similar to the one used in lab uses an oscillating motor at one end to vibrate a long rope with frequency f = 35 Hz and amplitude A = 0.25 m. The rope is held at constant tension by hanging a mass on the other end. The length of the rope is adjusted to form loops.The rope has mass density  µ = 0.020 kg/m, and tension T = 17.27 N. Assume that at t = 0 the end of the rope at x = 0 has zero y-displacement. What is the y-displacement of the piece of rope at x₁ = 0.40 m when t = 0?

Solution:
