Question
For example, the vectors B and In terms of components, you subtract vectors by simply subtracting ponents. For example, if tract B from Figure 3-14 (b). then Dr =A,-B, and of D are found, its magnitude and direct Once the components calculated as usual. EXERCISE 3-5 a. For the vectors given in Figure 3-12, find the components of D A-B b. Find D and and compare with the vector D shown in Figure 3-14 (b) .B SOLUTION . D,1.26 m, Dy 2.96 m b. D-3.22 m, --66.9° + 180°-113°. In Figure 3-14 (b ) we see that D is shorter than B, which has a magnitude of 4.00 m, and its direction somewhat greater than 90°, in agreement with our numerical results. angle is FIGURE 3-14 Vector subtraction (a) The vector B and its negative-B (b) A vector construction for D=A-BExplanation / Answer
The question posted in incomplete as i do not have the values for A and B
Anyhow, I am using the values provided in solution for part a)
From the graph 3-14 i know that D = A- B
ALso
Dx= -1.26
Dy = 2.96
Magnitude of D = (Dx^2 + Dy^2)^(1/2)
Hence
D = ((-1.26)^2 + 2.96^2)^(1/2) = 3.217 or 3.22
