92. A pulley of moment of inertia $2.0\mathrm{kg}?{\mathrm{m}}^2$ is mounted on a wall as shown in the following figure. Light strings are wrapped around two circumferences of the pulley and weights are attached. What are (a) the angular acceleration of the pulley and (b) the linear acceleration of the weights? Assume the following data: $r_1=50\mathrm{cm},r_2=20\mathrm{cm},m_1=1.0\mathrm{kg},m_2=2.0\mathrm{kg}$.
