Final answer:
The stopping distance for a vehicle traveling at 65 mph includes the distance covered during the driver's reaction time and the subsequent braking distance, which varies with road conditions and vehicle speed.
Step-by-step explanation:
The question on how many feet of stopping distance a vehicle has if driving at 65 mph involves calculating the total stopping distance, which includes both the driver reaction distance and the braking distance. The stopping distance is influenced by factors such as road conditions, vehicle speed, and driver reaction time.
In dry conditions, a car traveling at 65 mph (about 29.0 m/s) will cover more distance during the driver's reaction time compared to a car at a lower speed. The braking distance would then be calculated using the deceleration rate appropriate for the road condition (wet or dry).
To experiment the stopping distance, one could drive the car at exactly 50 mph and then apply the brakes until it stops, recording the time and using the deceleration rate to calculate the distance. However, for 65 mph, this would need to be adjusted accordingly, since speed predominantly determines stopping distance.
