Question:
In an attempt to estimate the speed of a vehicle just before it hit a signal pole, a traffic engineer measured the length of the skid maills made by the vehide and performed trial. runs at the site to obtain an estimate of the coefficient of friction. Determine the estimated anknown veloxity if the following data were obtained. length of skid marks = 585++, 590ft, 580 ft and 595 ft. speed of trial non = 30 mph. distance traveled during tral zun= 300 ft. Examination of the vehicle just after the crash indicated that the speed of impact was 35 mph.
