A wire of length l is kept just taut horizontally between two walls.A mass m hanging from its mid point depresses it by `delta`.Calculte the time in which a pulse set up at one end will reach the other end . The mass of the wire per unit length of it is `mu`

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 .
