If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve (a problem on icy mountain roads). (a) Calculate the ideal speed to take a 100.0 m radius curve banked at 15.0°. (b) What is the minimum coefficient of friction needed for a frightened driver to take the same curve at 20.0 km/h?

The banked turns at Talladega International Super Speedway are designed so a 1500 kg race car can drive around them at 340 km/h without slowing down. The radii of the turns are 350 m. a) If the force of friction is 3.0 x 104N [towards center], at what angle must the corners be at in order to allow this type of race? (Provide FBD) b) What is the slowest speed a car can travel and still be able to go around a comer without falling to the bottom of the track in km/h? (ignore friction)

A circular curve of highway is designed for traffic moving at 75 km/h. Assume the traffic consists of cars without negative lift. (a) If the radius of the curve is 260 m, what is the correct angle of banking of the road? (b) If the curve were not banked, what would be the minimum coefficient of friction between tires and road that would keep traffic from skidding out of the turn when traveling at 75 km/h? (a) Number Units (b) Number Units

The posted speed limit for a flat (unbanked) curve of radius 45m is 45mph. What is the required coefficient of static friction between the road and car tires for this turn to be negotiated safely?

b) The maximum speed that a car can turn a curve of 9.00 m radius without skidding is 70.0 mph (miles per hour). If the coefficient of friction between the tires and the road is 0.600, what is the rated speed of the banked curve? On a wet day, the same car begins to skid on the curve when its speed reaches 60.0 mph. What is the coefficient of friction in this case?   Please answer with complete solution and fre body diagram

A circular curve of highway is designed for traffic moving at 91 km/h. Assume the traffic consists of cars without negative lift. (a) If the radius of the curve is 150 m, what is the correct angle of banking of the road? (b) If the curve were not banked, what would be the minimum coefficient of friction between tires and road that would keep traffic from skidding out of the turn when traveling at 91 km/h? (a) Number i Units (b) Number Units

If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve (a real problem on icy mountain roads).   (a) Calculate the ideal speed to take a 105 m radius curve banked at 15.0∘?   . (b) What is the minimum coefficient of friction needed for a frightened driver to take the same curve at 10.0 km/h?
