Finding speed of a string given length, mass, and velocity of wave

Homework Statement


A string is 50.0 cm long and has a mass of 3.0 g. A wave travels at 5.0 m/s along the string. A second string has the same length, but half of the mass of the first. If the two strings are under the same tension, what is the speed of the second string?


The Attempt at a Solution


I don't know which equation to start with. I tried to find omega (w) using w=sqrt(g/l) and then using v=wrt. I don't think this is right. Can someone point me in the right direction?
