An object is moving along a straight line with a velocity that is initially positive (+u) and non-zero, but the acceleration is non-uniform and negative, such that the velocity eventually becomes negative (−v). What does the negative final velocity signify?
- A.The object has constant but negative acceleration.
- B.The object is moving backward relative to its initial direction.
- C.The acceleration became positive at some point.
- D.The object is at rest.
