A racing bus rounds a corner on a banked bus-racing track. The radius of curvature of the turn is R and the curve is banked with a grade G. If the coefficient of static friction between the tires and the road is μ, determine the range of speeds at which the bus can take the turn without slipping off the road.

[Answer: √ (?−?)/(1−??) < ? √?? < √ (?+?)/(1+??) ]
