(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A highway curve of radius 580m is designed for traffic moving at a speed of 70.0 km/hr.

2. Relevant equations

What is the correcting banking of the road?

3. 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!
