Required Information

A $46-$lb $($F$1)$ sliding panel is supported by rollers at $\backslash ($ B $\backslash )$ and $\backslash ($ C $\backslash ).$ A $\backslash (28-\backslash$mathrm$\{$lb$\}\backslash )($F$2)$ counterweight $\backslash ($ A $\backslash )$ is attached to a cable as shown and, in cases $($d$)$ and $($c$),$ is initially in contact with a vertical edge of the panel.

$($a$)$

$($b$)$

Neglecting friction, determine the acceleration of the panel and the tension in the cord immediately after the system is released from rest for case $($c$).$

The acceleration of the panel for case $($c$)$ is $\backslash (\backslash$quad $\backslash$mathrm$\{$ft$\}/\backslash$mathrm$\{$s$\}^\{2\}.\backslash$leftarrow $\backslash )$

The tension in the cord immediately after the system is released from rest for case $($c$)$ is

lb$.$
