Two blocks are positioned on surfaces as shown, and are convected by a cord, also as shown. Assume that at the positions' shown, Block $A$ is sliding downslope $($and therefore that Block $B$ is sliding upslope$).$

Find:

$($a$)a_{{?}_{?}}(A),a_B($megand dived

$($b$)$ the teasion $T$ in the cord

$($Assume that the cord remains tant$.)$
