A jogger travels a route that has two parts. The first is a displacement of 2.40 km due south, and the second involves a displacement that points due east.
(a) The resultant displacement + has a magnitude of 3.74 km. What is the magnitude of ?What is the direction of + relative to due south?
(b) Suppose that - had a magnitude of 3.74 km. What then would be the magnitude of and what is the direction of - relative to due south?
