Ajogger travels a route that has two parts. The rst is a displacement A of 2.90 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 A - B relative to due south?
