A circular curve of highway with radius 200m is designed for traffic moving at 100km/h, and is banked so that cars can make the curve even without friction at that speed.
What is the correct angle of banking for this curve?
Show steps, please.

Horizontal component = m v^2/R
Vertical component = m g
tan angle up from horizontal = v2/Rg
