Homework Help: College Physics

Posted by Anand on Monday, April 16, 2012 at 7:21pm.

A 30.0 m steel wire and a 22.0 m copper wire, both with 1.00 mm diameters, are connected end to end and stretched to a tension of 170 N. How long does it take a transverse wave to travel the entire length of the two wires? (Take the mass per unit length of the wires to be 7.006 g/m for copper and 6.173 g/m for steel.)

answer in seconds.

I tried:
V= sqrt(T/(M/L))
Vcopper= sqrt(170/(7.006/22))
Vsteel= sqrt(170/ (6.173/30))
Vcopper+Vsteel= incorrect answer

any help would be appreciated!
