(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

On a wet racetrack, the maximum safe speed, to avoid sliding on a level circular curve with a radius of curvature of 53 m, is 77 km/hr. What is the coefficient of friction between the car's tires and the track surface?

2. Relevant equations

(gravity)*(coefficient) = (v^2)/r

V= 21.39 m/s (after changing 77 km/hr into m/s)

Radius= 55 meters

3. The attempt at a solution

I kept getting the same answer .8488, but it keeps telling me i'm wrong? Help please!!!
