Mariah asked: Traveling at a speed of 13.3 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.650. What is the speed of the automobile after 1.22 s have elapsed? Ignore the effects of air resistance.

TmanBaller7 asked: A car and driver weighing 7330 N passes a sign stating “Bridge Out 29.8 m Ahead.” She slams on the brakes, and the car decelerates at a constant rate of 14.9 m/s2 .
The acceleration of gravity is 9.8 m/s2 . What is the magnitude of the work done stopping the car if the car just stops in time to avoid diving into the water?
Answer in units of J.

Fggfg asked: Suppose that the coefficient of kinetic friction of the rubber of a car tire and the street is = 0.8 k μ . What is the deceleration of a car on a flat street if the driver brakes sharply, so all the wheels are locked and skidding?

Cool =) Guy asked:
If the car runs out of brake fluid and the brakes dont work can you use the handbrake (E brake) to stop the car?
