The correct answer is:
d A represents the distance the dog traveled, while B is a vector representing the displacement of the dog.
Explanation:
- A represents the actual path length the dog followed, which is the distance traveled.
- B, being a vector, represents displacement, which is the straight-line distance from the starting point (P1) to the ending point (P2) in a specific direction. Displacement considers only the initial and final positions, not the actual path taken.
