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.

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...

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?
