I need help with this question. :) A model known as **stopping sight distance** 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:\[ S = \frac{V^2}{2g(f \pm G)} + TV, \]where we have the following:- \( S = \) stopping sight distance (ft)- \( V = \) initial speed (ft/s)- \( g = \) acceleration due to gravity, 32.2 ft/s\(^2\)- \( f = \) coefficient of friction between tires and roadways- \( G = \) grade of road- \( T = \) driver reaction time (s)---**Problem:**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.- Starting with the equation \( S = \frac{V^2}{2g(f \pm G)} + TV \), the units of \( S \) are ft, the units of \( V^2 \) are \(\_\_\_\_\), the units of \( g \) are ft/s\(^2\), and the units of the product \( TV \) are \(\_\_\_\_\). Rearranging the equation above to solve for \( f \pm G \), we obtain the following. (Use any variable or symbol stated above as necessary. Do not substitute numerical values; use variables only.)\[ f \pm G = \]- Then, the units of \( f \pm G \) are:\[\frac{\text{ft}^2/\text{s}^2}{\_\_\_\_\} = \_\_\_\_\ .\]
