2. For each situation, draw a vector diagram and calculate the resultant force: a) F1 = 150 N (west) and F2 = 420 N (East). Include a diagram. [2] b) F1 = 180 N at a bearing of 040 and F2 = 270 N at a bearing of 150. Include a diagram. [4] 3. Given EA = a, AB = b, and EH = C, as shown in the diagram below: a) Express an equal vector to c. [1 ] b) Express an opposite vector to a. [1 ] c) Express HF in terms of d, b, and C.[1 ] d) Express GA in terms of a, b, and C.[1 ] b A B G
