A car moving with a constant speed of 85 km/h enters a circular, flat curve with a radius of curvature of 0.40 km. If the friction between the road and the car’s tires can support a centripetal acceleration of 1.25 m/s2, without slipping, does the car navigate the curve safely, or does it fly off the road?

On a wet road, the coefficient of static friction between a car's tires and the flat road is 0.24. What is the maximum speed a car can safely navigate a turn with a 50.0 m radius of curvature?
A banked circular highway curve is designed for traffic moving at 62 km/h. The radius of the curve is 214 m. Traffic is moving along the highway at 41 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.)
A car of mass M = 1500 kg traveling at 55.0 km/hour enters a level turn (θ=0), and there is a coefficient of static friction μ between the road and the car's tires. What is μmin, the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 55.0 km/hour and that the radius of the curve is 65.4 m .
You are driving your car along a flat, curved road; the curve in the road is a segment of a circle with radius 50 meters. (We call this a "radius of curvature"). How fast can the car drive around the curve if the coefficient of static friction between the tires and the road is 1.0 (tires on dry pavement)? What if the coefficient of friction is 0.2 (tires on ice)?
A car is going along a circular road at a constant speed. The radius of the curve is 290 m, and the car takes 1.7 minutes to complete one round. Calculate its centripetal acceleration in m/s2.
