Question

When you're pulling out from an alley, driveway, or private road, you have to stop and yield to pedestrians before you get to a sidewalk.

a. True
b. False

Answer 1

The true or false statement about the displacement of two persons walking in the city is false because they have the same displacement regardless of the path taken, as displacement is the straight-line distance between the start and end points.

Step-by-step explanation:

The original question about pulling out from an alley and yielding to pedestrians does not directly pertain to the true or false statement; however, the act of walking in a city involves two-dimensional motion as does the scenario presented in the statement. When considering the displacement of two people walking in the city, we find that the magnitude of their displacement vectors will be the same if they cover the same ground no matter the order of movements because displacement is the straight-line distance between starting and ending points. Therefore, the answer to the true or false statement is:

b. False

The first person walking 2 blocks east and 5 blocks north and the second person walking 5 blocks north and then 2 blocks east will have the same displacement because they have covered the same ground in a city with uniformly squared blocks. Despite their different paths, the resulting displacements are equal in magnitude and both point from the starting to the ending position.
