A block, M$1,$ is resting on a horizontal surface with a coefficient of friction $=0\mathrm{.}288.$ A second block, M$2,$ is on a smooth ramp with an inclination of $=60.$ M$2$ has a mass of $10$kg$.$ They are connected with an inextensible cable which wraps partially around a drum. The drum has a coefficient of friction $=0\mathrm{.}387.(10$ points$)$ Calculate the tensions in the upper cable segment $($T$1)$ and the lower cable segment $($T$2).$ Then calculate the minimum mass, M$1,$ to prevent motion.
