Hints remaining: d duction 25% Part (b) what is the y-component of the vector V 3(A x 2B)? 25% Part (c) what is the z-component of the vector V-3(A × 2B)? 25% Part (d) what is the magnitude of the vector V?Explanation / Answer
A = 3.4 i + 2.1 j + 4.4 k
B = 8.7 i + 9.9 j + 11.4 k
2 B = 17.4 i + 19.8 j + 22.8 k
V = 3 ( A x 2B) = 3 (3.4 i + 2.1 j + 4.4 k) x (17.4 i + 19.8 j + 22.8 k) = 3 (-39.24 i - 0.96 j + 30.78 k)
V = -117.72 i - 2.88 j + 92.34 k
(a) x component of vector = - 117.72
(b) y component of vector = - 2.88
(c) z component of vector = 92.34
(d)magnitude of vector = 149.643
