Required information

Rod $\backslash ($ A B $\backslash )$ has a weight of $6\mathrm{.}800$ lb and is attached to a $11-$ lb cart $\backslash ($ C $\backslash ).$ The system is released from rest in the position shown and the effect of friction is neglected.

Determine the velocity of the cart $\backslash ($ C $\backslash )$ when the bar is in the horizontal position.

The velocity of the cart $\backslash ($ C $\backslash )$ is $\backslash (\backslash$mathbf$\{$v$\}\_\{$C$\}=\backslash )\backslash (\backslash$mathrm$\{$ft$\}/\backslash$mathrm$\{$s$\}\backslash$rightarrow $\backslash ).$
