Homework Statement
I need to write an equation for the at rest at a stoplight. Each car bumps into the one in front of it until the first car in line gets bumped.
Homework Equations
I found these equations for wave speed:
V=√(T/(m/L)), where T is tension, m is mass, L is length
and of course V=λf
The Attempt at a Solution
But both those equations have a time factor, and I wasn't given any time information. All I know is that wave speed needs to approach infinity as x → 0, and wave speed approaches vo as x→∞
Any hints would be appreciated.
