Post by: ppk on Apr 14, 2012
A 600-kg car is going around a curve with a radius of 120 m that is banked at an angle of 20° with a speed of 24.5 m/s. What is the minimum coefficient of static friction required for the car not to skid?
A) 0.12
B) 0.24
C) 0.36
D) 0.48
E) 0.60

can u please show how you got the answer?

If a curve with a radius of 84.0m is perfectly banked for a car traveling 68.8km/hr, what is the minimum coefficient of static friction for a car not to skid when traveling at 92.2km/hr?

Since friction is not required to provide the centripetal force for the car at 68.8km/h (the ideal speed)’ we can easily find the unknown banking angle. The normal force provides the centripetal acceleration; the horizontal component of the normal force is nsin\({\theta}\), so:
