A circular curve of highway with radius 200m is designed for traffic moving at 120km/h, and is banked so that cars can make the curve even without friction at that speed.
a) What is the correct angle of banking for this curve?
b) If the curve was NOT banked, what would the minimum coefficient of friction between the tires and the road need to be to keep cars from sliding out of the curve at 120km/h?
