Your instructor purchases a drone. He gets out of the roof of a building and flies the drone 140 meters straight west in 30 seconds, and then flies it 260 meters straight south for 120 seconds. He lets it hover stationary for 20 seconds, then flies it another 70 meters straight north in a span of 15 seconds, and finally 50 meters straight west in 12 seconds. 9. Calculate the net displacement from start and report this as a single magnitude and clearly identified direction. 10. What is the magnitude of the helicopter drone's average velocity over this entire excursion?

The layout of the town of Popperville is a perfectly square grid, with blocks 100 feet long (Fig. P3.8). A cat leaves her house and travels to Mike Mulligans place 4 blocks west and 3 blocks north of its starting point. After lapping up the milk that Mike always leaves out, the cat travels an additional 1 block north and 3 blocks east to Mrs. McGillicuttys house. a. On your paper, carefully copy the grid of streets that contains the cats house, Mike Mulligans house, and Mrs. McGillicuttys house. Then draw and label three displacement vectors on your sketch: r1, the cats displacement from her house to Mike Mulligans; r2, the cats displacement from Mike Mulligans to Mrs. McGillicuttys; and rtot, the cats total displacement. b. Write an equation to relate the three displacement vectors you have drawn. c. Is the distance the cat traveled greater than, less than, or equal to the magnitude of the cats total displacement vector? Explain. FIGURE P3.8
