An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks was 175ft. Use the formula s=24d−−−√ to find the speed of the vehicle before the brakes were applied. Round your answer to the nearest tenth.
Accepted Solution
A:
Answer:Speed before applying brakes = 64.8Step-by-step explanation:The formula is given as:[tex]s=\sqrt{24d}[/tex]Wheres is speed of car, andd is length of skid marksIt is given that d = 175 ft, so we substitute and find the speed of the car before the brakes were applied.[tex]s=\sqrt{24d}\\s=\sqrt{24*175}\\s=64.81[/tex]Rounding to nearest tenth, that is 64.8
