Final answer:
The stopping distance of a vehicle depends on reaction distance, perception distance, and braking distance. At a constant speed, the car will travel the reaction distance during the driver's reaction time plus the braking distance for a complete stop. Therefore, all the mentioned factors contribute to the total stopping distance.
Step-by-step explanation:
The stopping distance of your vehicle depends on a combination of multiple factors. These are: (a) reaction distance, (b) perception distance, and (strong)(c) braking distance. Therefore, the correct answer to the question is (d) All of the above.
When a driver sees a light turn red, the stopping distance will include the distance traveled during the perception and reaction time, as well as the braking distance on either dry or wet pavement. For instance, at a speed of 30.0 m/s with a reaction time of 0.500 seconds, the car will continue to travel for that duration before any braking action begins, and during this time, the assumption is that acceleration is zero and the velocity remains constant.
Once the braking process starts, the total stopping distance can be seen as a sum of the distance covered during the driver's reaction time plus the distance covered during the actual braking. Therefore, understanding these following factors is crucial for safe driving and stopping.
