Problem $12\mathrm{.}013-$ Two blocks connected by a pulley system

The two blocks shown are originally at rest. Neglect the masses of the pulleys and the effect of friction in the pulleys and

between the blocks and the Incline. Consider $m_A=212lb$ and $m_B=312lb.$

Problem $12\mathrm{.}013.$b $-$ Acceleration of the blocks

Determine the acceleration of each block. $($Round the final answer to three decimal places.$)$

The acceleration of block $A$ is

$(f\frac{t}{s^2}*7$

The acceleration of block $B$ is

~~$f\frac{t}{s^2}$
