Title: A 600-kg car is going around a curve with a radius of 120 m that is banked at an 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 Title: Re: A 600-kg car is going around a curve with a radius of 120 m that is banked at an Post by: robertling on Apr 15, 2012 Content hidden

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: See attachment: Title: Re: A 600-kg car is going around a curve with a radius of 120 m that is banked at an Post by: pup123109 on Nov 7, 2012 The answer is 0.1235 or A. :D
