We are building a road, and at one place we need to make a turn with a radius of 30m.  The coefficient of static friction between rubber and the material we are using is 0.6. Instead of keeping the road flat, let's bank the turn a little bit, giving the road an angle of 20﻿∘ above the horizontal. With the banked turn, what is the maximum speed a car could have and still make it around the turn without sliding?
