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

If a curve with a radius of 85m is properly banked for a car traveling 65 km/h what must the coefficiant of static friction be for a car not to skid when traveling at 95km/h

2. Relevant equations

For this question i tried using a few equations such as centripical force, force friction where Ffric = UsFn aswell as (mv^2)/R = Ffric i also though the equation Tan(theta)=V^2D/Rg was pertanent.

3. The attempt at a solution

I set up a proportion of mv^2/R = Us(ma) and the masses canceled out so i was left with v^2/ra but i didnt really know where to go from here.
