Answer:
D) The horse’s velocity increases by 2 mi/h every 1 s as the horse moves south
Explanation:
Let's analyze all options:
A. The horse’s speed changes to 2 mi/h as the horse moves south The horse's speed is not 2 mi/h, but it increases 2 mi/h every second. So, this is false.
B. The horse’s speed decreases by 2 mi/h every 1 s. It would only decrease if the horse was moving north. Otherwise this is false.
C. The horse’s position decreases by 2 mi every 1 s as the horse moves south. It is not horse's position but its velocity what changes 2mi/h every second. Also false.
D. The horse’s velocity increases by 2 mi/h every 1 s as the horse moves south. Since given acceleration is positive, you can say that its velocity increases 2mi/h every second. So, this is true
