4) For the vectors given in the following figure, use a graphical method to find the following resultants: (a) A + B (b) C - D (c) D + 2A (d) C - 2B . For each of these you must measure and report the length and angle (Accuracy counts on these so use a protractor and a ruler). YA X A 60 A = 10.0 B = 5.0 C = 12.0 D = 20.0 30 C 530 37
