A non-uniform wire of length l and mass ...

A non-uniform wire of length `l` and mass `M` has a variable linear mass density given by `mu = kx`, where `x` is distance from one end of wire and `k` is a constant. Find the time taken by a pulse starting at one end to reach the other end when the tension in the wire is `T`.
