2. Using the following x and y components, draw the resultant vector and solve its magnitude and direction. a) x: 3.4 y: 2.7 b) x: 5.6 y: -7.1 c) x: -211 y: -44.0

3. Add the following vectors using the add components method. Draw the resultant and ESTIMATE its magnitude and direction. a) 256 [25 o N of E] + 313[5 o S of W] b) 15.6 [35 o W of N] + 8.82 [72 o W of S] + 33.3 [27 o S of W]
4. A sailboat is heading due north at 7.2 knots. The ocean current is due east at 1.2 knots. What speed and direction is the sailboat tracking? (Find the answer by adding the components)
5. A B747 is crossing the Pacific at 420 knots heading West. Air Traffic Control radar is tracking the plane at 470 knots [12 o S of W]. What is the wind speed and direction? (HINT: Remember which vector is the resultant.)
