What are the displacements for the following vectors?

I. A vector moving 45 degrees northeast at a velocity of 3m/s and the turns 30 degrees southeast

Since you don't give any time values, there's no way to figure displacements.

Also, the vector does not move; some object does.

Also, your explanation is odd. How do you turn southeast? You can turn 30 degrees clockwise, which is toward the SE. Or do you mean that the vector is now E30S or S30E?
