Unformatted text preview: A and B in Fig 1.27, use a scale drawing to find the magnitude and direction of a) the vector sum A + B ; b) the vector difference A B . From your answers to part (a) and (b), find the magnitude and direction of c) A B ; d) B A. Fig. 1.27 1.35. Compute the x- and y-components of the vectors A , B , and C in Fig. 1.28. Fig. 1.28 1.45. Write each vector in Fig. 1.28 in terms of the unit vectors i and j . 1.50. For the vectors A and B and C in Fig 1.28, find the scalar products a) A B , b) B C ; c) A C . 1.68. a) Find the magnitude and direction of the vector R that is the sum of the 3 vectors A, B and C in Fig. 1.28. In a diagram, show how R is formed from the 3 vectors in Fig. 1.28. b) Find the magnitude and direction of the vectors S = C A B . In a diagram, show how S is formed from the 3 vectors in Fig. 1.28....
