A weight is hung over a pulley and attached to a spring composed of two parts, each made of the same material but one having $4\mathrm{.}1$ times the mass per unit length of the other. The string is plucked so that a pulse moves along it at a speed v$1$v$1$ in the heavier part and at speed v$2$v$2$ in the lighter part.

What is the ratio v$1/$v$2$v$1/$v$2?$

v$1/$v$2=$v$1/$v$2=(0\mathrm{.}01)$
