Two masses $\displaystyle \mathrm{m}_1=5 \mathrm{~kg}$ and $\displaystyle \mathrm{m}_2=10 \mathrm{~kg}$, connected by an inextensible string over a frictionless pulley, are moving as shown in the figure. The coefficient of friction of horizontal surface is 0.15. The minimum weight m that should be put on top of $\displaystyle \mathrm{m}_2$ to stop the motion is :
