Number 1 and 2

1) Is it possible to have A + B = A -B|=? If so, illustrate with a diagram. 2) For the three vectors shown in the figure, take A = 1.50 m, B = 2.00 m, and C = 1.00 m. Find graphically: (a) A + B + C; (b) A - B - C. Use a protractor and rules since neatness counts. 70 A 1.5 m 20 60 B C 2 m 1 m
