Let us revisit the problem from Chapter $6$ of two masses connected by a string passing over a pulley only now we will include the rotational contribution of the pulley $($see Figure $10\mathrm{.}10).$ Let $M=5kg$ and $m=3kg$ as before. Treat the pulley as a disk with a mass of $0\mathrm{.}2$ kg and $r=0\mathrm{.}1$ m $.$ Determine the $($a$)$ acceleration of the two blocks and $($b$)$ the tension in the two ropes. Hint: The tension in the two ropes are not the same.
