The $2\mathrm{.}1-$kg collar is pulled by a cord that passes around a small peg at $\backslash ($ C $\backslash ).$

$($Figure $1)$

If the cord is subjected to a constant force of $\backslash ($ F$=60\backslash$mathrm$\{$~N$\}\backslash ),$ and the collar is at rest when it is at $\backslash ($ A $\backslash ),$ determine its speed when it reaches $\backslash ($ B $\backslash ).$ Neglect friction. Express your answer to three significant figures and include the appropriate units.
