Answer:
The distance which the car skid is
Explanation:
From the question we are told that
The initial velocity of the car is
The coefficient of kinetic friction is
According to the law of energy conservation
The initial Mechanical Energy = The final Mechanical Energy
The initial mechanical energy is mathematically represented as
where KE is the initial kinetic energy which is mathematically represented as
And PE is the initial potential energy which is zero given that the car is on the ground
Now
Where is the work which friction exerted on the car which is mathematically represented as
Where is the distance covered by the car before it slowed down
=>
