Question

A car that travels twice as fast as another when braking to a stop will skid ________ times as far. The skidding distance depends on the mass of the cars.

Answer 1

A car that travels twice as fast as another when braking to a stop will skid four times as far.

Step-by-step explanation:

The skidding distance of a car depends on its braking distance, which is determined by the deceleration of the car. The braking distance is inversely proportional to the square of the deceleration. Therefore, if a car travels twice as fast as another when braking to a stop, it will skid four times as far. This is because the deceleration is the same for both cars, but the braking distance is four times larger for the faster car.
