We've measured the tire skid marks and the Distance(D) of the skid marks is D = 120 feet'. Since all four tires were locked and skidding we've determined the vehicle breaking system is working with 100% breaking efficiency, also our road grade and super-elevations are "0". example coding scheme qualitative research
