wariber [46]

Complete Question

The complete question is  shown on the first uploaded image  

Answer:

The distance which the car skid is  l  =  \frac{v_i^2 }{2 *  \mu_k  * g }

Explanation:

From the question we are told that  

     The  initial velocity of the car is  v_i

     The  coefficient of kinetic friction is  \mu_k

According to the law of energy conservation

    The initial Mechanical Energy =  The final  Mechanical Energy  

                           M_i  = M_f  

The initial mechanical energy is  mathematically represented as  

              M_i  =  KE _o  + PE_e

where KE is the initial kinetic energy which is  mathematically represented as

        KE  =  \frac{1}{2} m v_i^2

And  PE  is  the initial potential energy which is  zero given that the car is  on the ground

     Now  

           M_f =  W_{\mu}

Where  W_{\mu} is  the work which friction exerted on the car  which is  mathematically represented as

       W_{\mu} =  m*  \mu_k  *  g  *  l

Where  l is the distance covered by the car before it slowed down

        \frac{1}{2} m v_i^2  = m*  \mu_k  *  g * l

=>     l  =  \frac{v_i^2 }{2 *  \mu_k  * g }
