Question
The Antilock Braking system in newer car is a computer- based senor system designed to detect and prevent skidding by keeping the brakes from locking. in this problem, an older car, without ABS, is moving down the road at a speed, v. Ahead is an accident. the driver has two choices to stop;either lock the brakes and skid to a stop , or pump the brakes, keep the wheel rolling until coming to a stop. which will get the car to stop more quickly? why? identify any assumptions you make in aswering this question.
Explanation / Answer
The correct option is to pump the breaks because rolling grip diminishes rapidly and sliding friction provides a greater proportion of the force that slows the vehicle. Due to local heating and melting of the tyres, the sliding friction can be very low. When braking at, or beyond, the peak braking force the steering is ineffective since the grip of the tyre is entirely consumed in braking the vehicle.
When you just push the breaks once you allow the tires to slip more and the time of stop is longer while when you pump the brake you diminish the sliping time
