Final answer:
A motorist must learn to drive in reverse for the driving test, and experiments for stopping distances are critical for road safety. Understanding vehicle control in various scenarios is essential for a driver's education.
Step-by-step explanation:
It is true that a motorist must be able to drive in reverse to pass the road portion of the driving test, often requiring the driver to back the vehicle about 100 feet in a straight line, slowly and smoothly. This question relates to a practical aspect of driving skills necessary for the safe operation of a vehicle. Understanding how to control a vehicle in reverse is crucial for maneuvering in various traffic situations and parking environments. When designing an experiment to measure stopping distances, one must consider several factors: the initial speed of the vehicle, reaction time, road conditions, and how data will be collected. An example experiment could involve driving the car at a set speed, such as 50 mph, and then applying the brakes until the vehicle stops while recording the distance taken to halt. This information is important for understanding vehicle dynamics and safety on the road.
When assessing whether it is safe to cross the road upon observing a car 28 meters away, factors like the speed of the car and the pedestrian's walking speed must be considered. If a car is moving on a straight road at a consistent speed and in a single direction, it can be assumed to continue this motion unless acted upon by another force, according to Newton's first law of motion.
