Answer:
9.5 m/s.
Step-by-step explanation:
The cat's final velocity can be calculated using the following equation:
final velocity = initial velocity + acceleration * time
- Initial velocity = 5 m/s
- Acceleration = 1.5 m/s²
- Time = 3 s
Plugging these values into the equation, we get:```
final velocity = 5 m/s + 1.5 m/s² * 3 s
= 9.5 m/s
Therefore, the cat's final velocity is 9.5 m/s.
