7. (Transportation) Stopping sight distance (SSD) is defined as the distance needed for a driver to see an object on the roadway and then stop before colliding with it. It's composed of the distance to react on first seeing the object and then the distance to stop after the brake is engaged. The following is a formula for determining stopping sight distance: SSD = cort coz ** 28 (f+G)) SSD is the stopping sight distance (m or ft). c is the conversion factor - .278 m-hr/km-s (metric units) or 1.47 ft-hr/mi-sec (U.S. Customary units). v is the speed (km/hr or mi/hr). r is the reaction time (sec). g is the acceleration caused by gravity - 9.81 m/s2 or 32.2 ft/sec f is the road's coefficient of friction (dimensionless). G is the road grade, as a decimal (dimensionless). Using this equation, write, compile, and run a C++ program that first prompts the user for the unit system to use (metric or U.S. Customary units). Based on the response, your program should select the correct conversion factor, request the remaining data, and display the stop ping sight distance. Use your program to complete the following chart
