Problem
A drone starts from rest at point , flies east, and then north. The total time taken for the two legs is . a. Find the magnitude of the drone's average velocity. b. State its direction with respect to the east.Intuitive explanation
The key is separating displacement from distance traveled. The drone moves along two perpendicular paths (east then north), so use the Pythagorean theorem to find the straight-line displacement from start to finish. Then think about what "average velocity" or "average speed" means—distance over time versus displacement over time—depending on what the problem asks you to find.
