here we have to keep in mind that the work done by the friction force has to be equal to the kinetic energy change, so we can write: \[\Large {\mu _k}mgd = \frac{1}{2}m{v^2}\] where m is the mass of your car, and d is the requested distance. Furthermore g is the earth gravity, and v is the velocity of our car

i am referring to your answer given above - ie 89m. |dw:1435912972594:dw| i get \(\frac{50,000^2}{3600^2 \times 2 \times 1.1 \times 9.8} = 8.95m\)
