Vector {A} points in the negative y direction and has a magnitude of 8 units. Vector {B} has twice the magnitude and points in the positive x direction. Find the direction and magnitude of vector A - vector B, vector B - Vector A
Vector A points in the negative y direction and has a magnitude of 8 units. Vector B has twice the magnitude and points in the positive x direction. Find the direction and magnitude of vector A + vector B.
Three vectors have the same magnitude. The magnitude of each of these vectors is M. The first vector A points in the positive x direction. The second vector B points in the negative y direction. The third vector C points in the positive z direction. These three vectors added together are equal to a fourth vector D. What is the magnitude of the fourth vector?
