4. Analyze the module of vector A analytically, knowing that Ax = 3u and Ay =...
Sarah choose for the class four vectors A, B, C, and D with components: Ax=23.5, Ay= -9.7; Bx=-17.3, By=2.3; Cx=51.9, Cy=-32.5; Dx=-10.1, Dy=-12.2. Determine magnitude and direction (as measured from the positive x-axis) of the vector A+B-C-D *the answer my professor gave was 51.6, -46(angle)
