1. The problem statement, all variables and given/known data A car rounds a slippery curve. The radius of curvature of the road is R, the banking angle is theta and coefficient of friction is mu. What should be the cars speed in order that there is no frictional force between the car and the road? 2. Relevant equations F=mv^2/r 3. The attempt at a solution In general, I have no idea how the components or forces work for banking curves, so an explanation and help would be greatly appreciated.
