$9.(10\mathrm{.}16)$ A $12\mathrm{.}0$ kg box resting on a horizontal, frictionless surface is attached to a $5\mathrm{.}00$ kg weight by a thin, light wire that passes over a frictionless pulley. The figure shows a $12\mathrm{.}0$ kilogram box on a horizontal surface. The box is attached to a $5\mathrm{.}00$ kilogram weight by a wire that passes over a pulley at the right edge of the horizontal surface. The pulley has the shape of a uniform solid disk of mass $2\mathrm{.}60$ kg and diameter $0\mathrm{.}500$ m $.$ After the system is released, find the tension in the vertical segment of the wire. $35\mathrm{.}6$ N
