Answer :
Final answer:
The acceleration of the car in front when it brakes, considering an average human reaction and the provided conditions, is approximately 9.14 m/s².
Explanation:
This question is about calculating the acceleration of the car in front when it brakes. The acceleration due to braking is calculated by multiplying the coefficient of friction with gravitational acceleration. For this case, the coefficient of friction is given as 0.933 and the gravitational acceleration is 9.8 m/s².
Therefore, the acceleration of the car in front when it brakes would be: 0.933 * 9.8 = 9.14 m/s² (approximately).
