Final answer:
The stopping distance of the car on wet concrete is 5.97 meters.
Step-by-step explanation:
To find the stopping distance of the car, we can use the formula d = v^2 / (2a), where d is the distance, v is the initial velocity, and a is the acceleration.
Given that the car is skidding to a halt on wet concrete, we can use the coefficient of kinetic friction (μk) to calculate the acceleration.
The formula is μk = a/g, where g is the acceleration due to gravity. Rearranging the formula, we have a = μk * g.
Plugging in the values, we have a = 0.40 * 9.8 m/s^2 = 3.92 m/s^2.
Substituting the values into the initial formula, we have d = (14 m/s)^2 / (2 * 3.92 m/s^2) = 5.97 m.
Therefore, the stopping distance of the car is 5.97 meters on wet concrete.
