The components of vector A are Ax = +2.2 and Ay = -6.9 , and the components of vector B are given are Bx = -6.1 and By = -2.2. What is the magnitude of the vector B - A
For simplicity, let's call vector B-A vector C Then C is Cx = (-6.1 - 2.2) Cy = (-2.2 - (-6.9)) Or, Cx = -8.3 Cy = 4.7 The magnitude is found with the Pythagorean theorem ||C|| = √(-8.3² + 4.7²) = 9.538
