Problem: The vector A = (4.0meters)i + (-3.0meters)j Find a) its magnitude and b) its angle in relation to i. Question: I know magnitude is a scalar but dont know what I am really trying to find in this problem. Am I looking for the direct point from the start of i to the end of j? Do I just need to use the pythagoream therom to find the magnitude. To find its angle do I just need to use tangent?
