A curve of radius 180 m is being designed in a new highway to allow cars travelling at 70 km/hr to round the curve with zero frictional forces. a.) At what angle must the road be banked? b.) What is the minimum coefficient of friction that will allow a car to successfully go around the curve at 30 km/hr?

In 1959, Daytona Speed was added to the NASCAR racing circuit and introduced 31° banked curves for racing. This allowed stock cars to reach much higher speeds (around 200 mph) during a race. Today the steepest banked curves are found at Talladega Motor Speed Way at 33° with a turn radius of 1100 ft. The flattest track in NASCAR is Hew Hampshire Motor Speed Way with banked curves of 7° with a turn radius of 410 ft. a) Assuming no friction, what are the max speeds (in mph) without slipping toward the outer edge of the track at the Talladega and NH Motor Speedways? b) With friction (assume μs of 1.1 between the tires and the track)?

What has to be the radius R, in order for the static friction to provide adequate Centripedal force? LOOK AT PICTURE

A car drives around two circular curves on two different roads. The two curves have the same radius of curvature. And coincidentally, the maximum speed that the car can drive through either of the turns is the same for both roads. The first road is frictionless, but it is banked at 14.5 degrees from the horizontal. The other turn is flat. What is the coefficient of friction between the car tires and the road on the unbanked turn?

Problem 1: What is the ideal speed to take a 100 m radius curve that's banked at a 20° angle? "Ideal" in this context means the centripetal force is provided entirely by the horizontal component of the normal force with no need for static friction between the tires and the ground.

A car rounds an unbanked curve of radius 65 m. If the coefficient of static friction between the road and car is 0.72, then answer the following questions. (a) What force provides the centripetal force? A. Weight of the car B. Normal force on the car from the road C. Force of static friction (b) What is the maximum speed at which the car can traverse the curve without slipping? Enter to 2 significant figures Vmax= 18.07 m/s

A car is trying to make a turn on a banked curve on a very icy day and the frictional force between the tires and road is zero. The curve has a radius of 50 m and the car is moving at 12 m/s. What angle should the curve be banked at for this to happen safely?
