Which object is most likely represented by the motion map

This is the motion map that represents the car (or the object). We model the position of the car (or the object) with a small point or dot. At each position, the car’s (or object's) velocity is represented by an arrow (or vector). In this motion map, the four dots represent the car at each of four seconds. The arrows (vectors) are all the same length and point in the same direction because the car is always traveling with the same speed (arrow length) and in the same direction (arrow points to the right).
