Question
A curve in a road 8m wide has a radius of 60 m. How much higher than its inner edge should be the other edge of the road be if it is to be bunked properly at 20 km/hr?

change km/hr to m/s
Net force from centripetal and gravity shouuld be a some angle theta.
Tan theta= v^2/r / g= v^2/rg
solve for theta
Now, the outer edge:
SinTheta=outeredgeincrease/8m
solve for outer edge increase
