A jogger travels a route that has two parts. The first is a displacement A→ of 2.80 km due south, and the second involves a displacement B→ that points due east. The resultant displacement A→ + B→ has a magnitude of 3.90 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 3.90 km. (c) What then would be the magnitude of B→, and (d) what is the direction of A→⋅B→ relative to due south?

Multiple Concept Example 9 reviews the concepts that play a role in this problem. As an aid in working this problem, consult Concept Simulation 1.1. Two forces are applied to a tree stump to pull it out of the ground. Force F→ A has a magnitude of 1820 newtons (N) and points 38.0∘ south of east, while force F→ B has a magnitude of 2760 N and points due south. Using the component method, find the (a) magnitude and (b) direction of the resultant force F→A + F→ B that is applied to the stump. Specify the direction as a positive angle with respect to due east. (a) Number Units (b) Number Units
