Answer :
Final answer:
The stopping distance for dry concrete, including the reaction time, is 3.28 m.
Explanation:
The stopping distance when the surface is dry and µdry = 0.609 can be calculated by adding the distance traveled during the driver's reaction time to the stopping distance. Assuming a constant velocity during the reaction time of 0.500 seconds, the stopping distance can be found. Given that the car initially travels at 30.0 m/s, the stopping distance for dry concrete, including the reaction time, is 3.28 m (option c).
