1. The problem statement, all variables and given/known data I've managed to solve a few, but a few major problems are bugging me (quite a few, unfortunately.) The first question is this: "A golfer takes two putts to sink his ball in the hole once he is on the green. The first putt displaces the ball 1.10 m east, and the second putt displaces it 8.27 m south. What displacement would put the ball in the hole in one putt? Answer in units of m" Easy, pythagorean theorem... however, the second part, is confusing me: "What is the direction (measured from due east, with counterclockwise positive) of the displacement? Answer in units of ◦." I drew it out, and managed to get something like 277.5764903.. not sure if it's correct, I got ~82.4 on the angle, and then subtracted that from 90 and then added 270 (because I'm assuming they're telling us to start at E... which is "0")? The 2nd confusing question... "The eye of a hurricane passes over Grand Bahama Island. It is moving in a direction 88.5◦ north of west with a speed of 43.7 km/h. Exactly 3.10 hours later, the course of the hurricane shifts due north, and its speed slows to 20.2 km/h, as shown. How far from Grand Bahama is the hurricane 4.87 h after it passes over the island? Answer in units of km." I'm in a tad of a hurry to finish my PreCalc homework, so I'll post up what I did for the hurricane question later. Please help me out! I get vectors OK, but this has gotten me stumped. Thanks alot! Jake.
