$($

Two blocks are positioned us shown, and connected by a cord in the manner depicted.

Given: $V_{A_0}=3$ftslongleftarrow $($initial velocity at $k=0)$

$a_B=$ constant $($TBD$)$

after $B$ has me xed by $x_B=26$ in longrightarrow, then $v_A=5\frac{f}{s}$larr

Find: Cassuming that the cood remains tout

$(NB$:$V_A,not{V}_B)$
