Homework Help: Physics

Posted by Andrea on Wednesday, February 6, 2008 at 5:40pm.

A string of mass m=.1kg is stretched to where its length is L=20m. What is the tension force applied to the string if it takes a pulse 2 seconds to get from one end to the other?

m=kg
L=20m
T=4s
mass density =m/L = .1/20 = kg/m
Tension =?

I know v=sqrt(F_t/mass density) But I'm given two unknowns. How would I find velocity?
