Final answer:
The weasel is approximately 16.5616 meters away from Farmer Bob when he notices after 2.52 seconds.
Step-by-step explanation:
To find the distance between the weasel and Farmer Bob after 2.52 seconds, we can use the equation d = vt, where d is the distance, v is the velocity, and t is the time. Here, the velocity of the weasel is given as 6.58 m/s and the time is 2.52 seconds.
So, d = (6.58 m/s)(2.52 s) = 16.5616 m.
Therefore, the weasel is approximately 16.5616 meters away from Farmer Bob when he notices after 2.52 seconds.
