0 9. (II) Three vectors are shown in Fig. 3-35. Their magnitudes 22 are given in arbitrary units. Determine the sum of the three vectors. Give the resultant in terms of (a) components (b) magnitude and angle with the +x axis. 23 AA =44,0) 28.0° 56.0 FIGURE 3-35 (C-31.0) Problems 9, 10, 11, 12, and 13. Vector magnitudes are given in arbitrary units 10. (II) (a) Given the vectors A and B shown in Fig. 3-35 determine B - A. (b) Determine A - B without using your answer in (a). Then compare your results and see if they are opposite 11. (II) Determine the vector A - , given the vectors Ä and C in Fig. 3-35.

(11) Suppose a vector v makes an angle with respect to the y axis. What could be the x and y components of the vector V? 15. (II) The summit of a mountain, 2450 m above base camp is measured on a map to be 4580 m horizontally from the camp in a direction 38.40 west of north. What are the compo- nents of the displacement vector from camp to summit?Explanation / Answer
12 a) B -3A = (-26.5 cos 56 degree - 44*3* cos 28 degree) i
+ 26.5 sin 56 degree - 44*3* sin 28 degree
= -131.37 i - 40j
b) 2A-3B+2C = (2*44 cos 28 degree + 3*26.5* cos 56 degree) i + (2*44* sin 28 degree - 3*26.5* sin 56 degree - 2*31 )j
= 122.16 i -86.59 j
