Longitudinal Wave properties

  1. Nov 25, 2008 #1
    This one has me pretty well stumped, I've tried several methods and I am basically getting tunnel vision now. Any help would be appreciated.

    1. The problem statement, all variables and given/known data
    (a) Show that the speed of a longitudinal wave along a spring of force constant 'k' is v=[tex]\sqrt{kL/\mu}[/tex], where L is the unstretched length of the spring and [tex]\mu[/tex] is the mass per unit length.

    (b) A spring with mass .4kg has an unstretched length of 2m and a froce constant of 100 N/m. Use results of (a) to solve.

    2. Relevant equations



    3. The attempt at a solution
