Final answer:
A motorist's time management system should ensure adequate time and space to stop or slow the vehicle if necessary, accounting for road conditions, driver reaction time, and initial vehicle speed.
Step-by-step explanation:
A motorist's time management system should indeed ensure an adequate time and space to stop or slow the vehicle if necessary.
This is certainly true as the stopping distance of a vehicle depends on various factors including road conditions, driver reaction time, and the initial speed of the vehicle.
For example, it takes longer to stop a vehicle on wet pavement as compared to dry pavement, accounting for both the increased braking distance and the reaction time before applying the brakes.
Additionally, traffic signals are designed to control the flow of vehicles and ensure their safe stopping when necessary, thereby preventing accidents.
When a car is initially traveling at a speed of 30.0 m/s, the stopping distance will vary depending on whether the pavement is dry or wet. The driver's reaction time, often assumed to be around 0.500 seconds, also contributes significantly to the total stopping distance, which is the sum of the distance traveled during the reaction time and the braking distance. This illustrates the importance of maintaining appropriate speeds and allowing for sufficient stopping distances in response to traffic signals and road conditions for safety.
