Question
A car enters a circular flat curve with a radius of curvature of 0.40 km with a maximum speed of 130 km/h. If the friction between the road and the car's tires can supply a centripetal acceleration, what is the static coefficient of friction?

R = 400 meters
v = 130,000/3600 = 36.1 m/s
Ac = v^2/R
= 3.26 m/s^2
Ac/g = mu = 3.26/9.81 = .322
v = 130,000/3600 = 36.1 m/s
Ac = v^2/R
= 3.26 m/s^2
Ac/g = mu = 3.26/9.81 = .322
