Part 1 of 4 DO . P = 677,000 people. (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 Compute: driver slams on the brakes vary depending on the square of the speed of the car? N = 29.6 x 677,000 = 20,039,200 kg. The length of skid marks varies directly |as the square of the speed at which the car was traveling when the brakes were applied. So, about 20,039,200 kg of newsprint would be needed (= 20,039.2 metric tons). Part: 1 / 4 M Verify with tutor Part 2 of 4 (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 applied. Use k for the constant of variation. solve this The equation of variation is. 0=0 Answer explanation by Al X Answer: directly Explanation: Braking distance (and skid-mark length) is proportional to the square of the vehicle's speed, due to kinetic energy - mu that must be dissipated by friction. Therefore, if speed doubles, skid length becomes four times as long: it varies directly with v. 1 2 3 Ask Al your follow up question. Do not enter personal information.
