Question

Consider an infinitesimal segment of the string located at distance x = 1.00 m from the tip of the lever, at t = 20.0 ms. At t= 20.0 ms, the perturbation has already reached that segment but the wave has not reached the pulley yet (so there is no reflected wave). Confirm this. How far from its equilibrium position is this segment at t= 20.0 ms? Is it below or above its equilibrium position? What is the velocity of this segment at t = 20.0 ms? Give the magnitude and direction. Explain the difference between your answer to the previous question and the wave speed.

y = (0.500cm)sin((2.00x10^-4)t)

T = 3.14x10^-4 s & Amplitude = 5x10^-3 m & m = 1 kg & Length of the string = 5 m & the mass density of the string = 1.50x10^-3 kg/m
