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

Which of the following is correct?

• Initial Position = -2 m

  Final Position = 0 m

  Distance = 14 m

  Displacement = 2 m

• Initial Position = 0 m

  Final Position = -2 m

  Distance = 14 m

  Displacement = -2 m

• Initial Position = -2 m

  Final Position = 0 m

  Distance = -2 m

  Displacement = -2 m

• Initial Position = -2 m

  Final Position = 0 m

  Distance = 14 m

  Displacement = 14 m
