Problem $5-$ Stopping sight distance on horizontal curve

A simple horizontal circular curve is designed on a two$-$lane highway $($one lane in each direction$)$ with $11-$ ft lanes, and the radius $($measured to the roadway centerline$)$ of $770$ ft $.$ The curve is designed with $\backslash (8\backslash \%\backslash )$ superelevation, and the middle ordinate necessary to provide stopping sight distance $($Ms$)$ of $25$ ft $.$ Does this curve satisfy the requirements for design speed of $\backslash (50\backslash$mathrm$\{$mi$\}/\backslash$mathrm$\{$h$\}\backslash )?$
