Question

Use the motion map to answer the question.

A motion map. The position line is a long black arrow pointing right, labeled x. Above the line are 2 dots with a vector pointing away from x that start at x, each one shorter. Above that are two yellow vectors pointing toward x, each positioned to the left of a dot. A vertical row of 3 black dots appear in the center of the position line, where the bottom dot is aligned with the yellow arrows and the top dot has a vector pointing away from the origin. There is one other dot with a longer vector arrow to the right of the top dot. Above this line are 2 yellow arrows pointing away from the origin.

Which scenario could be represented by the motion map?

A car speeds up to merge onto the freeway and then continues at a constant velocity.
A car speeds up to pass a truck, then slows down to a constant velocity.
A car slows to stop at a stop sign. Once traffic is clear, the car speeds up.
A car slows to makes a U-turn, then continues in the opposite direction.

Answer 1

Answer: A car slows to makes a U-turn, then continues in the opposite direction.

Reason: The map shows velocities that change sign (arrows pointing one way, then later pointing the opposite way) with a vertical cluster of dots (positions close together) indicating it slows/stops before reversing and then a longer arrow after the stop showing it speeds up in the opposite direction.
