Final answer:
It is generally required to stop before crossing a sidewalk when driving out of a private road or driveway for pedestrians' safety. The displacement for two persons walking in a city, regardless of their different paths, is the same since displacement depends on the start and end points.
Step-by-step explanation:
When driving from a private road or driveway, it is generally required to stop before crossing a sidewalk. This law is in place to ensure safety for pedestrians who may be using the sidewalk.
Therefore, the answer to the question, 'Do you have to stop before crossing a sidewalk when driving from a private road or driveway?' is True.
Regarding the True or False question about displacement: A person walks 2 blocks east and 5 blocks north. Another person walks 5 blocks north and then two blocks east. The displacement, which is the shortest distance from the starting point to the final position, would be the same for both individuals since displacement only depends on the initial and final positions, not the path taken.
Thus, the statement is False; the displacement of the first person will not be more than the displacement of the second person as they would have the same resulting vector from their starting point to their final destination.
