A racing track has a corner which is banked at an angle of 30 degrees(adsbygoogle = window.adsbygoogle || []).push({});

cars passing round the corner travel in an acr of a circle of radius 20 metres.

car is travelling at 30 m/s and using g as 10 instead of 9.81

I need to find the smallest value of the coeffiecent of friction needed to prevent the from slipping sideways......but i dont know what forces that i need to use...they havent give the mass the car so im not to sure about the reaction...also air resistance do i include?

Is there any one that can show how to do it the steps and the forces i need to resolve...thankz
