Consider the pulse described in terms of its displacement at t = 0 by: C y(x,t)|t=0 = 2+x where C is a constant. a. Draw the wave profile (i.e. y(x, 0)). b. Write an expression for the wave, having a speed v in the -x direction, as a function of time. c. If v = 1 m/s, sketch the profile at t = 2 s.
