Final answer:
The time it takes for a car moving at 60 mph to stop completely would likely exceed 6 seconds. The correct time range cannot be precisely determined without the specific deceleration rate at 60 mph, but it is likely to be in the range of 8 to 10 seconds or 10 to 15 seconds based on typical stopping distances.
Step-by-step explanation:
To determine how long a car moving at 60 mph will take to come to a complete stop, we need to consider the car's deceleration rate. Even though the provided reference information speaks of a car traveling at different speeds and decelerating at different rates, we can infer that at a speed of 60 mph (approximately 27 m/s), a car would need a significant distance and time to stop, depending on various factors such as road conditions and the car's braking capabilities.
Given that the provided reference information states a deceleration rate on dry concrete of up to 7.00 m/s², which is a good deceleration rate that would likely correspond to favorable conditions, it still does not directly reference the deceleration rate for a car traveling at 60 mph. However, from the information discussed, we can suggest that the time it would take to stop would likely exceed the 3 to 6 seconds range and would probably be more than 6 seconds.
The precise answer largely depends on the deceleration rate and cannot be accurately concluded from the information provided without knowing the specific deceleration rate at 60 mph. Nonetheless, based on typical stopping distances and times, the closest estimates among the given choices would likely be in the range of 8 to 10 seconds or 10 to 15 seconds, but this is speculative without precise data.
