I am stuck on two problems and I keep getting them wrong. Its been a while since I did vectors so I'm a little rusty.
1. Bob walks 200 m south, then jogs 730 m southwest, then walks 200 m in a direction 27.0 degrees east of north. What is the distance and angle?
2. A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 6.0m/s. A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 8.0m/s relative to the air, what direction should they head in order to move directly south?
I know these are probably simple, but I'm banging my head on these two. For problem 1, I tried graphically to resolve the vectors using tip to tail but my apporach. Promlem 2 if the wind is blowing from the west so its 6m/s east?
