Final answer:
Turning right onto a one-way street is different from turning onto a two-way street due to traffic flow and lane positioning. In the examples given, displacement remains the same regardless of the order of directions taken when the distances are equal in a city block scenario.
Step-by-step explanation:
Making a right turn onto a one-way street is indeed different than making a right turn onto a two-way street. When turning onto a one-way street, you typically stay in the lane closest to you after you turn, which could be the left or right side depending on the direction of the one-way traffic. In contrast, making a turn onto a two-way street requires you to enter the lane nearest the right-hand side of the road to ensure you do not interfere with oncoming traffic from the opposite direction.
In the case of displacement and direction in a city setting, like the scenarios described in the references, the path taken can result in different outcomes. Displacement is a vector quantity; it has both magnitude and direction. In the first scenario, if the person walks 2 km east and then 1 km north, his total displacement would be different if he took a wrong turn and walked in the opposite direction for the second leg. In the second scenario, regardless of the order of the streets walked (east then north, or north then east), the displacement of both persons would be the same because they've covered the same distance in each direction.
