Question:

A jogger travels a route that has two parts. The first is a displacement A of 2.50 km due south, and the second involves a displacement B(vector) that points due east.

(a) The resultant displacement A(vector) + B(vector) has a magnitude of 3.75 km. What is magnitude of B, and what is the direction of A(vector) + B(vector) relative to due south?

(b) Suppose that A(vector) – B(vector) had a magnitude of 3.75. What then would be the magnitude of B, and what is the direction of A(vector) – B(vector) relative to due south?
