Two blocks are connected by a string, as shown in the figure. The smooth inclined surface makes an angle of $\backslash$theta $=44\backslash$deg with the horizontal, and the block on the incline has a mass of

$5\mathrm{.}7*$kg$.$ The mass of the hanging block is $6*$kg$.$ Initially both blocks are at the same height $($as in the figure$)$ and moving at $3*($m$)/($s$),$ with the hanging block moving down. How fast are they

moving when the hanging block has fallen $2*$m $?$
