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

know that the coefficients of friction between the blocks and the inclines are ${}_s=0\mathrm{.}25$ and ${}_k=0\mathrm{.}20.$ Consider

$m_A=200lb$ and $m_B=300lb.$

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

The acceleration of block $A$ is

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

The acceleration of block $B$ is

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

$u$
