Final answer:
The question regarding the average speed of a cheetah during a 28-minute and 25-second sprint cannot be accurately answered without more data on the distance covered or the cheetah's velocity over time.
Step-by-step explanation:
The question is asking to find the average speed of a cheetah during a sprint, not the acceleration during the sprint itself. The information provided about acceleration tells us that a cheetah can accelerate from rest to 30.0 m/s in 7 seconds; however, that rate is not sustained for the entire duration. The average speed of a cheetah over an extended period of a sprint is going to be less than its peak speed because it includes the time spent accelerating to and decelerating from that peak speed. Without additional information about the total distance covered or the specifics of the cheetah’s velocity profile throughout the 28 minutes and 25 seconds, we cannot accurately calculate the average speed.
