Question: A light string with a mass per unit length of 8.00 g/m has its ends tied to two walls separated by a distance equal to

A light string with a mass per unit length of 8.00 g/m has its ends tied to two walls separated by a distance equal to three fourths of the length of the string (Fig. P16.30)
An object of mass m is suspended from the center of the string, putting a tension in the string.
(a) Find an expression for the transverse wave speed in the string as a function of the mass of the hanging object.
(b) What should be the mass of the object suspended from the string in order to produce a wave speed of 60.0 m/s?
