Speed of Propagation vs. Particle Speed. (a) Show that Eq. (15.3) may be written as y1x, t2 = Acosc 2p l 1x - vt2 d (b) Use y1x, t2 to find an expression for the transverse velocity vy of a particle in the string on which the wave travels. (c) Find the maximum speed of a particle of the string. Under what circumstances is this equal to the propagation speed v? Less than v? Greater than v?
