**Vector Subtraction** 1) Subtract the following vectors: a) 12 N at 40° S of E - 6 N at 20° W of S [Image of a vector diagram] Result: 11.6 N at 10.5° S of E b) 1.8 m/s at 45° W of N - 1.0 m/s at 70° W of N [Image of a vector diagram] Result: 0.99 m/s at 20° W of N c) 17 m due east - 5 m due west [Image of a vector diagram] Result: 22 m due east 2) A cat walks 17 m due north. It is later seen 22 m due east of its starting point. What was its change in displacement? [Image of a vector diagram] Result: 27.8 m at 37.69° N of E 3) A bird can fly at 6.0 m/s and is pointed due west. From the ground it appears to be traveling at 10.0 m/s at 53° S of W, what is the wind's velocity? [Image of a vector diagram] Result: 8.0 m/s due south **Answers** 1a) 11.6 N at 10.5° S of E 1b) 0.99 m/s at 20° W of N 1c) 22 m [E] 2) 27.8 m at 37.69° N of E 3) 8.0 m/s due south
