The pulse is moving in the positive x direction with a speed v_{0}.
(a) Sketch a graph showing the shape of the spring at a later time, t = t_{0}. Specify the height and position of the peak in terms of the symbols given.
(b) Write an equation for y(x, t) the displacement of the spring for any time, t.
(c) Calculate and sketch a graph of the upward velocity of the spring, v(x, t_{0}) as a function of the position on the spring at the time t_{0}.
