1) Anja is driving west in a straight line. After driving for 5.50 km, she turns south, and drives for 9.20 km. At the end of her drive, what is the magnitude of her displacement?
2) A team of biologists are tracking the motion of a mountain lion. The lion walks north for 880 meters, then turns and walks west for 1760 m. What is the displacement vector for the lion's motion?
3) A metro train starts from a terminal station. The train heads north for 475 m, then west for 165 m, then north for 410 m, then east for 650 m where it arrives at the next station. What is the magnitude of the displacement vector from the terminal station to the next station?
