A person walks 50 meters directly north, stops, and then travels 32 meters directly south.  What is their displacement?

• 82 meters
• 18 meters
• 28 meters

Which of the following is correct?

• Initial Position = -5 m

  Final Position = -5 m

  Distance = 22 m

  Displacement = 0 m

• Initial Position = -5 m

  Final Position = -5 m

  Distance = 0 m

  Displacement = 22 m

• Initial Position = -5 m

  Final Position = 6 m

  Distance = 22 m

  Displacement = 0 m

• Initial Position = -5 m

  Final Position = 6 m

  Distance = 0 m

  Displacement = 22 m
