The sliders A and $B$ are connected by a light rigid bar and move with negligible friction slot. For the position shown, the hydraulic cylinder imparts a velocity and acceleration to slider A of $0\mathrm{.}4\frac{m}{s}$ and $2\frac{m}{s^2}$ respectively, both to the right. Determine the acceleration of slider B and the force in the bar.

ANSWER:

$a_B=-2\mathrm{.}37\frac{m}{s^2}$

$T=8\mathrm{.}21(N)$
