> > The x component of vector A is 8.7 units, and its y component is -6.5 units. What is the magnitude of A ? > > The components of vectors A and B are given as follows: Ax = 7.6 Bx = -5.1 Ay = -9.2 By = -6.8 > > What is the magnitude of the vector difference B A ? The figure shows four vectors A , B, C , and D, having magnitudes 10.0 m, 8.00 m, 6.00 m, and 2.00 m, respectively. Find the magnitude of the sum of these four vectors. B 30 30 X D
