Here's the problem: A uniform rope with length L and mass m is held at one end and whirled in a horizontal circle with angular velocity omega. You can ignore the force of gravity on the rope. Find the time required for a transverse wave to travel from one end of the rope to the other. So far by fiddling with some equations, I've got: v = sqrt(F_tension/µ) F_tension = ma = m*L*omega^2 µ = m/L v = sqrt((m*L*omega^2)/(m/L)) = sqrt(omega^2*L^2) = omega*L And of course, that gets me nowhere except another textbook equation, namely v = R*omega So I have no idea where to go from there. Any help will be appreciated.
