Required information

A $8-$ kg block $\backslash ($ m $\backslash )$ is attached to link $\backslash ($ A B $\backslash )$ and rests on a moving belt. The values of $\backslash (\backslash$mu$\_\{$s$\}\backslash )$ and $\backslash (\backslash$mu$\_\{$k$\}\backslash )$ are $0\mathrm{.}30$ and $0\mathrm{.}25,$ respectively. Neglect the weight of the link.

Determine the magnitude of the horizontal force $\backslash (\backslash$mathbf$\{$P$\}\backslash )$ that should be applied to the belt to maintain its motion to the left. The magnitude of the horizontal force $\backslash (\backslash$mathbf$\{$P$\}\backslash )$ that should be applied to the belt to maintain its motion to the left is
