Braking distance (and skid-mark length) is proportional to the square of the vehicle's speed, due to Part 1 of 4 kinetic energy , my that must be dissipated by friction. Therefore, if speed doubles, skid length becomes four times as long: it varies directly with v. (a) When a car stops rapidly, the wheels lock and the tires skid across the road, leaving behind marks. How does the length of skid marks left when a driver slams on the brakes vary depending on the square of the speed of the car? DO 2 3 The length of skid marks varies directly |as the square of the speed at which the car was traveling when the brakes were applied. Sources Part 2 of 4 1 . UC Berkeley Course 2 Australian 3 1GENERAL Notes Title.. Curriculum Multi-. PROCEDURES 2 3. (b) Write an equation of variation that describes the relationship between the length of skid marks L and the velocity of a car v when the brakes were qt1vp7t2dp.pdf 9.1.1b Bodyworks.doc policeoperatingpro... applied. Use k for the constant of variation. M Verify with tutor The equation of variation is 1 = kv. Alternate Answer: solve this The equation of variation is L = kv- . Answer explanation by Al Answer: I = k v^2 Step-by-step: Part: 2 / 4 . The problem states the skid-mark length varies directly as the square of the speed. "Varies directly with v^2" means I is proportional to v^2. Part 3 of 4 . Introduce the constant of variation k to write the equation: I = k v^2. (c) At 40 miles per hour (under ideal conditions) skid marks would be 70 feet long. Use this information to find a specific value for the constant of variation in your equation. Do not round. The value of the constant of variation k is X Ask Al your follow up question. Do not enter personal information.
