Final answer:
The stone is approximately 38.28 meters away from the base of the cliff.
Step-by-step explanation:
To find the distance the stone is from the base of the cliff, we can use the horizontal speed of the stone and the time it was in the air. The formula to calculate distance is distance = speed x time. In this case, the initial horizontal speed of the stone is 5.8 m/s and the time in the air is 6.6 seconds. Plugging these values into the formula, we get:
Distance = 5.8 m/s x 6.6 s = 38.28 meters
So, the stone is approximately 38.28 meters away from the base of the cliff.
