Two cables of equal diameter and length, one made of aluminum and the other made of steel, are welded together and strung horizontally under tension. When the aluminum end is struck, a wave pulse propagates from the end at a velocity of 15 m/s.
(a) The wave pulse crosses over the weld and onto the steel part of the cable. What is the velocity of the wave as it travels in the part made of steel?
(b) If the total length of the cable is 10 m, how long does it take the wave pulse to reflect off the far end and return? Note that these are not sound waves, but transverse waves like those on a string. Also, you may want to consult Table 10.1 for the densities of aluminum and steel.
