Two blocks of masses $m_1=14,5kg$ and $m_2=5,3kg$ are connected by a rope that hangs over a pulley as shown in the figure. The pulley is a uniform disk of radius $R=0,45m$ and the mass $M=9,6kg.$ The system is released from rest. Determine the magnitude of the acceleration of the blocks. Express your answer in units of $\frac{m}{s^2}$ using one decimal place. Take $g=9\mathrm{.}80\frac{m}{s^2}.$

Note: The moment of inertia of a uniform disk is $I_{\text{d}\text{i}\text{s}\text{k}}=\frac{1}{2}M{R}^2.$ Assume the rope is massless and it does not slip over the pulley.
