8. Speed from Skid Marks When a car makes an emergency stop on dry pavement, it leaves skid marks on the pavement. The length L, in feet, of the skid mark is related to the speed S, in miles per hour, when the brakes were applied. The relationship is S(L) = 5.06/L. a. Make a graph of S versus L. Include lengths of up to 200 feet. b. A man involved in an emergency stop claimed that his speed was between 30 and 40 miles per hour. What skid mark length would support this claim? 240 5.06
