A jogger travels a route that has two parts. The first is a displacement A of 2.25 km due south, and the second involves a displacement B that points due east. The resultant displacement A + B has a magnitude of 4.10 km. (a) What is the magnitude of B, and (b) what is the direction of A + B as a positive angle relative to due south? Suppose that A - B had a magnitude of 4.10 km. (c) What then would be the magnitude of B, and (d) what is the direction of AB relative to due south?
