9. A clothesline has a linear mass density of 0.28 kg/m, and isstretched with a tension T = 30 N. One end is given a sinusoidalmotion with a frequency of 5.0 Hz and amplitude of 0.010 m. At thetime t = 0 the end has zero displacement and is moving in thepositive direction.
(a) Find the wave speed, the amplitude, the frequency, period,wavelength, and the wave
number, of the wave motion.
(b) Write a wave function describing the wave.
(c) Find the position of the point at x = 0.25 m at time t = 0.10sec.
