An apparatus similar to the one used in lab uses an oscillatingmotor at one end to vibrate a long rope with frequency f = 40 Hzand amplitude A = 0.25 m. The rope is held at constant tension byhanging a mass on the other end. The rope has mass denstiy ? = 0.02kg/m and tension T = 20.48 N. Assume that at t = 0 the end of therope at x = 0 has zero y-displacement and is moving downward. Whatis the y-displacement of the piece of rope at x1 = 0.5 m when t =0? y1 =
