Final answer:
To find the total displacement, add the three vector displacements graphically.
Step-by-step explanation:
To find the total displacement of a person who walks three different paths on a flat field, we can use the graphical technique for adding vectors. First, we add the 25.0 m displacement in a direction 49.0° north of east to the previous displacement. Then, we add the 23.0 m displacement heading 15.0° north of east. Finally, we add the 32.0 m displacement in a direction 68.0° south of east. Adding these vectors graphically will give us the total displacement.
