$2.(40$pts$)$ A cable is wound around a uniform solid cylinder with a given diameter of $39\mathrm{.}0$ cm and mass $25\mathrm{.}0$ kg that can rotate freely about its axis. The cable is a little stuck, so your friend helps. One of you pulls on it at an angle of $163\mathrm{.}3$ with a force of $95\mathrm{.}5$ N and the other pulls at an angle of $194\mathrm{.}18$ with a force of $112$ N $($see Fig. $2).$

Assuming that the cable unwinds without slipping or stretching, find the tangential acceleration of the drum.
