Financial Algebra © Cengage/South-Western Slide 1 5-9 ACCIDENT INVESTIGATION DATA Determine the minimum skid speed using the skid mark formula. Determine the minimum skid speed using the yaw mark formula. OBJECTIVES
Financial Algebra © Cengage Learning/South-Western Slide 2 accident reconstructionist skid mark shadow skid mark anti-lock braking system (ABS) yaw mark S = skid speed formula S = skid distance drag factor braking efficiency chord (C) middle ordinate (M) r = Key Terms
Financial Algebra © Cengage Learning/South-Western Slide 3 Example 1 A car is traveling on an asphalt road with a drag factor 0.78. The speed limit on this portion of the road is 35 mi/h. The driver just had his car in the shop and his mechanic informed him that the brakes were operating at 100% efficiency. The driver must make an emergency stop, when he sees an obstruction in the road ahead of him. His car leaves four distinct skid marks each 80 feet in length. What is the minimum speed the car was traveling when it entered the skid? Round your answer to the nearest tenth. Was the driver exceeding the speed limit when entering the skid?
Financial Algebra © Cengage Learning/South-Western Slide 4 Example 2 Melissa was traveling at 50 mi/h on a concrete road with a drag factor of 1.2. Her brakes were working at 90% efficiency. To the nearest tenth of a foot, what would you expect the average length of the skid marks to be if she applied her brakes in order to come to an immediate stop?
Financial Algebra © Cengage Learning/South-Western Slide 5 Neil is traveling on a road at M miles per hour when he slams his foot on the brake pedal in order to avoid hitting a car up ahead. He is traveling on a gravel road with a drag factor of A and his brakes are operating at 100% efficiency. His car leaves three skid marks of length x, y, and z, respectively. Write an algebraic expression that represents the skid distance. CHECK YOUR UNDERSTANDING
Financial Algebra © Cengage Learning/South-Western Slide 6 EXAMPLE 3 An accident reconstructionist took measurements from yaw marks left at a scene. Using a 43-foot length chord, she determined that the middle ordinate measured approximately 4 feet. The drag factor for the road surface was determined to be 0.8. Determine the radius of the curved yaw mark to the nearest tenth of a foot. Determine the minimum speed that the car was going when the skid occurred to the nearest tenth.
Financial Algebra © Cengage Learning/South-Western Slide 7 Determine the minimum speed of a car at the point the brakes are immediately applied to avoid a collision based upon a yaw mark chord measuring 62.4 feet and a middle ordinate measuring 5 feet. The drag factor of the road surface is 1.2. Round your answer to the nearest tenth. CHECK YOUR UNDERSTANDING
