Final answer:
The physics concept in the question deals with the appropriate speed limit when approaching an intersection to ensure the safety of pedestrians crossing the road, which is to approach at 16 miles per hour (25.75 km/hr). This speed allows enough time for someone to cross at least 4 meters in distance before a vehicle reaches them. Observing speed limits helps in avoiding traffic tickets and ensuring safety.
Step-by-step explanation:
The question pertains to the physics of motion, specifically relating to speed limits and the distance required for crossing a road safely in relation to the speed of oncoming vehicles. To approach an intersection at 16 miles per hour, which is equivalent to roughly 25.75 kilometers per hour, is to maintain a speed that gives pedestrians enough time to cross the road safely. It is important to adhere to the speed limit to ensure the safety of all road users and to avoid potential traffic violations.
The rule of thumb when crossing the street is to ensure you can walk at least 4 meters, which is 2 meters further than the average car width, before a car reaches you. This is crucial if the car is traveling at the city speed limit of 60 km/hr. For drivers, it's essential to adhere to the speed limits to prevent accidents and to avoid getting a speeding ticket. The given information suggests a need to maintain control over vehicle speed, especially when approaching an intersection where the speed limit is enforced and pedestrians may be crossing.
