I am new to the forum and was hoping if someone could explain to me how to do this problem, give me some formulas, or even possibly give me an answer. :) It is from my Giancoli Fifth Edition High School Physics book.(adsbygoogle = window.adsbygoogle || []).push({});

If a curve with a radius of 80m is perfectly banked for a car traveling 70km/hr, what must be the coefficient of static friction for the car not to skid when traveling 90km/hr?

Any/all help is greatly appreciated.
