Suppose we have a system of strings composed of length L each. A block of mass M = 12 Kg is hung at the free end of the string of linear mass density u1 and a transverse wave is generated that propagates throughout the composite system. The ropes have the same cross-sectional areas A and m is unit mass m = 3kg

Consider that only transverse waves are produced. Determine the time it takes for this transverse pulse in terms of ?(L/g) to traverse the entire composite string if it is generated at the end of the string of linear density u1
