The diagram shows a motion map for a train. A motion map. The position line is a long black arrow pointing right that is labeled x. Above the line are three dots with a vector pointing away from x that start farther right from x. There are three black dots that are in a vertical column above the point of the third vector. There are two yellow vectors with no black dots pointed toward x starting just above the vertical column of three dots. Which statement is supported by the motion map? The train traveled south and then north. The train moved at a velocity of 75 mph north. The train had a greater velocity when it moved away from the origin. The train stopped for 3 seconds.
