Question

A model known as stopping sight distances=2g(f±G)V2VwhereSVgfGT= stopping sight distance (ft) 

is used by civil engineers to design roadways. This simple model estimates the distance a driver needs in order to stop his car while traveling at a certain speed after detecting a hazard. The model proposed by the American Association of State Highway Officials (AASHO) is given by

+T

= initial speed (ft/s) = acceleration due to gravity, 32.2 ft/s 2= coefficient of friction between tires  and roadways = grade of road = driver reaction time (s) 

What are the appropriate units for f and G if the preceding equation is to be homogeneous in units? Show all steps of your work.
