Energy in a Triangular Pulse a triangular wave pulse on a taut string travels in the positive x-direction with speed u. The tension in the string is F, and the linear mass density of the string is µat t = 0, the shape of the pulse is given by
(a) Draw the pulse at t = O.
(b) Determine the wave function y (x. t) at all times t.
(c) Find the instantaneous power in the wave. Show that the power is zero except for -L
