Hey
The proper velocity or optimum v on a road banked by an angle θ with the horizontal is given by
v = [rg(µs + tan θ)/(1−µs tanθ)]½
where r = radius of curvature of road, g = acceleration due to gravity , µs = coefficient of friction between road and tyres.
Substituting
r = 1000 m, µs = 0.5, tan θ = 1, g = 9.8 m/s2,
we get
v = 171.46 m/s
