Two masses at rest are connected by a string at rest, to a pulley and hung over the edge of a table where mass $1$ is on the table and mass $2$ is hanging off. The table is flat and NOT RAISED ON AN INCLINE. If the co$-$efficient of static friction and coefficient of kinetic friction are given as $\mathrm{.}7$ and $\mathrm{.}5$ respectively, find The mass of block $2$ that will barely set mass $1$ into motion provided the mass of mass $1$ is $\mathrm{.}7$kg$.($note this is the same as asking what is the biggest mass m$1$ can be while keeping the system STATIONARY$).$
