Answer:
Coefficient of friction will be 0.587
Explanation:
We have given mass of the car m = 500 kg 
Distance s = 18.25 m
Initial velocity of the car u = 14.5 m/sec
As the car finally stops so final velocity v = 0 m/sec
From second equation of motion 



We know that acceleration is given by 



So coefficient of friction will be 0.587
