As shown in the figure, with $\backslash ($ x$\_0=5$m $\backslash ),\backslash ($ h $=50$m $\backslash ),$ and a parabolic curve of $\backslash ($ z $=14\mathrm{.}95$x$^\{0\mathrm{.}75\}\backslash ),$ there is a dam. Calculate $($a$)$ the $**$horizontal force $\backslash ($ F$\_$H $\backslash )**$ acting on the dam and its point of application $\backslash ($ h$\_$p $\backslash ),$ and $($b$)$ the $**$vertical force $\backslash ($ F$\_$V $\backslash )**$ acting on the dam and its point of application $\backslash ($ x$\_$p $\backslash ).[2$ points$]$ The length of the dam is $\backslash ($ L $=100$m $\backslash ),$ and the unit weight of water is $**1$ tonf$/$m$^3**.|$
