Answer:
-0.5 m/s²
Explanation:
Step 1: Given data
- Initial velocity of the dog (u): 7.5 m/s
- Final velocity of the dog (v): 0 m/s (Stop)
Step 2: Calculate the acceleration of the dog
The acceleration (a) is equal to the change in the velocity over the time elapsed.
a = v - u / t
a = 0 m/s - 7.5 m/s / 15 s
a = -0.5 m/s²
