Which description best represents the motion shown in the velocity time graph

• objects start at rest, moves in the negative direction then turns around to move with a positive velocity

• object starts moving the in the negative direction, stops, then in the positive

• object starts moving in the positive direction, turns around to move in the negative before coming to a stop.

• The objects starts slowly in the positive direction then speeds up, still moving in the same direction.
