1. Using the diagram below, write a. AF in terms of AB b. AF in terms of AB and BC. C E D B 2. Add the following vectors using the Triangle Law. a. 9 N on a heading of [S2.W] and 11 N on a heading of [N31 .W]. b. 7 m/s on a bearing of 30 and 2 m/s from a bearing of 343. [HINT: a vector "on" a bearing extends "out" from the origin and a vector "from" a bearing is directed in "toward" the origin] 3. Add the following vectors using the Component law. a. 9 m/s [N30 E] and 2 m/s [N 60 E]. b. 3 N in a direction 15 south of west and 4 N in a direction 12 east of south. 4. A plane is heading on a bearing of 200 with an airspeed of 400 km/h when it is blown off course by a wind of 100 km/h from the northeast. Determine the resultant ground velocity of the plane
