You're designing a highway so that the maximum centripetal acceleration on a curve is no more than 1.0 m/s^2. What is the minimum curvature radius to accommodate a 100 km/h maximum speed?

On a highway curve with radius 30 m, the maximum force of static friction (centripetal force) that can act on a 1,273-kg car going around the curve is 9,127 N. What speed limit should be posted for the curve so that cars can negotiate it safely?
A car rounds a curve of radius 30 m. If the maximum centripetal acceleration is 5m/s2, what is the maximum speed of the car in kilometers per hour?
A highway curve of radius 68.0 m is banked at 21.4 degree so that a car traveling at 26.4 m/s (95 km/hr) will utilize both banking and friction to keep it on the curve. Determine the minimum coefficient of static friction between the tires and the road to keep the car on the road at this speed on this curve.
7. A highway curve with a radius of R metres is banked so that cars moving at v m/s around the curve do not have to rely on friction when taking the turn. IWPS 7. No.4] 7.1 Show (from first principles) that the angle, 6, at which, the road should be banked is given by: 0 arctan 7.2 A particular banked highway curve with a radius of 200 m is designed for traffic moving at 60 km/h. On a rainy...
9. When designing winding roads through the country-side, civil engineers need to take into consideration the maximum safe sideways acceleration (centripetal acceleration from friction) for rounding a turn is ac 1 m/s2. What is the minimum radius of the curve in the road if the maximum speed is 45 mph? (Ans: 404.7 m)
Highway curves are "banked" inward, so gravity assists the car's traction. Suppose another highway curve has a radius of curvature of 500m. It is banked so that traffic moving at 30m/s can travel around the curve without needing any help from friction. a) Draw a force diagram for a car traveling around this curve at a constant speed. Draw the diagram so that you are looking at the rear of the car. Do not tilt your coordinate axes for this...
highway curves are often banked, so the normal force provides the centripetal force and cars don’t have to rely on friction. After having responded to an emergency call in the middle of a snowstorm, an ambulance is speeding back towards the hospital along a slippery curved road. Your job is to inform the ambulance driver of the maximum speed at which he can travel around this curve without slipping up the bank. You are told that the curve has a...
A curve of radius 70 m is banked so that a 1000 kg car traveling at 60 km/h can round it even if the road is so icy that the coefficient of static friction is approximately zero. The acceleration of gravity is 9.81 m/s 2 . a) Find the minimum speed at which a car can travel around this curve without skidding if the coefficient of static friction between the road and the tires is 0.2 b) Find the maximum...
When a fighter pilot makes a very quick turn, he experiences a centripetal acceleration. When this acceleration Is greater than about 4 times g the pilot will usually lose consciousness ("black out"). Consider a pilot flying at a speed of 800 m/s who wants to make a very sharp turn. What is the minimum radius of curvature that he can take without blacking out?
The radius of curvature of a highway exit is r = 49.5 m. The surface of the exit road is horizontal, not banked What is the minimum required value of the coefficient of static friction between the tires of the car and the surface of the road so that the car can safely exit the highway at a constant speed of 42.0 km/h without sliding?
