Question:
Two masses $\mathrm{m}_{1}=5 \mathrm{~kg}$ and $\mathrm{m}_{2}=10 \mathrm{~kg}$, 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 $m_{2}$ to stop the motion is :-
