A hiker’s trip consists of three segments. Path A is 9.0 km long heading 60 degrees north of east. Path B is 8.0 km long in a direction due east. Path C is 3.0 km long heading 315 degrees counterclockwise from east. Find the hiker’s displacement (magnitude and displacement) in order A, B, C and in order C, B, A. What can you conclude about the resulting displacements?
