ok, i have a problem and its answer, but im not sure how to get the answer:(adsbygoogle = window.adsbygoogle || []).push({});

Police lieutenants, examining the scene of an accident involving two cars, measure the skid marks of one of the cars, which nearly came to a stop before colliding, to be 81 m long. The coefficient of kinetic friction between rubber and the pavement is about 0.70. Estimate the initial speed of that car assuming a level road.

the answer is 33.34.

I can't figure out how to get that answer.
