    Answer: B

    Explanation:

    Velocity is the distance covered in a specific direction per time taken. It is a vector quantity.

    When an object reaches terminal velocity, the velocity will be constant.

    But a ride that spins clockwise and then counterclockwise. Will experience many changes in velocity. Since velocity is a vector quantity which has both magnitude and direction.

    Change in direction is tantamount to change in velocity. Therefore, the scenario that describes a change in velocity is a  ride that spins clockwise and then counterclockwise
