A jogger travels a route that has two parts. The first is a displacement of 2.80 km due south, and the second involves a displacement that points due east. The resultant displacement + has a magnitude of 4.25 km. (a) What is the magnitude of , and (b) what is the direction of + as a positive angle relative to due south? Suppose that - had a magnitude of 4.25 km. (c) What then would be the magnitude of , and (d) what is the direction of - relative to due south?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
