Beatrice Clay · Answer 1

Constant speed but different velocity

Explanation:

Since the car speed at the corner is 90km/h which is the same as before. The speed, or magnitude of the velocity vector, remains unchanged. The direction of the velocity vector, on the other hand, is changing as the car turns around the corner. Therefore, the car maintains a constant speed, but not a constant velocity.
