Q1. Before starting this problem, review Conceptual. The force vector A has the magnitude of 75.0 newtons (N) and points due east. The force vector B has a magnitude of 101 N and points 72.9 ° north of east. Find (a) magnitude and (b) direction of A - B. (Give the direction as the positive angle with respect to due east). Find (c) magnitude and (d) direction of B - A. (Give the direction as a positive angle with respect to due west).
