Homework Statement
A highway curve of radius 580m is designed for traffic moving at a speed of 70.0 km/hr.
Homework Equations
What is the correcting banking of the road?
The Attempt at a Solution
I tried using tanθ=v^2/rg
Also I converted the 70 km/hr into m/s by 70 km/hr(1000 m/km/3600 s/h)=19.44 m/s
So I ended up with 19.44m/s^2/580m(9.8m/s^2)=.066°
It's wrong
Any help is appreciated!
