The graph shows the object's motion. Which sentence is a correct interpretation?

• The object rolls along a flat surface. Then it rolls forward down a hill, and then finally stops.

• The object doesn't move at first. Then it rolls forward down a hill and finally stops.

• The object is moving at a constant velocity. Then it slows down and stops.

• The object doesn't move at first. Then it moves backwards and then finally stops.

• The object moves along a flat area, moves backwards down a hill, and then it keeps moving.
