Antilock brakes. A car travels at 65 mi/h when the brakes are suddenly applied. Consider how the tires of a moving car come in contact with the road. When the car goes into a skid (with wheels locked up), the rubber of the tire is moving with respect to the road; otherwise, when the tires roll, normally the point where the tire contacts the road is stationary. Compare the distance required to bring the car to a full stop when (a) the car is skidding and (b) when the wheels are not locked up. Assume the coefficients of friction between the tires and the road are 0.80 and 0.90. (c) How much farther does the car go if the wheels lock into a skidding stop? Give your answer as a distance in meters and as a percent of the nonskid stopping distance. (d) Can antilock brakes make a big difference in emergency stops? Explain.
