6. A car turning on a banked road, considered frictionless (say, covered with ice), negoti- ates the turn at 65 miles per hour. If the radius of curvature R is 85 meters, what is the banking angle 0? If, on another day the road is without ice and a car is seen to negotiate the same banked road at 95 miles per hour. What is the coefficient of static friction if the car is not to skid when taking the turn?

Not sure how to do this

Why are turns on a racetrack banked? Imagine a turn in the road has a radius of curvature of 70-meters andis banked at an angle of 15◦. At what speed can a car turn without the assistance of friction?

2. It takes a 615 kg car 14.3 s to travel at a uniform speed around a level circular path of 50.0 m radius. (a) What is the speed of the car? (b) What is the acceleration of the car? (c) What amount of centripetal force must the track exert on the tires as it moves in the circle?

positivephysics An engineer is trying to determine the maximum speed at which a 700kg car can travel around the curve. The coefficient of friction between the wheels and the road is 0.3. Answer questions for the case when the car is traveling at the maximum speed. Number of forces: Force(s) towards center: Are all forces balanced?

Problem 1. What is the maximum speed with which a 2,000-kg car can round a turn of radius 75.0 m on a flat (horizontal) road if the coefficient of static friction between the tires and the road is 0.600? What angle should the turn be banked to keep the car on the bank at this speed if the coefficient of static friction is changed to 0 (an iey curve)?

A stunt driver determines that the fastest speed at which he can take an unbanked curve without sliding is 30 mph. If the curve has a radius of 25 m what must be minimum coefficient of static friction between the road and the car tires? Does it depend on the car’s mass?

Horizontal Circle - Unbanked Curve. What us the maximum speed at which a racing car can round a curve of 80m radius on a level road if the coefficient of friction between the tires and the road is 0.44?

Need help checking practice problems, image included. Thanks!

11. A crate of eggs is located in the middle of the flatbed W of a pickup truck as the truck negotiates a curve in the flat road. The curve may be regarded as an arc of a circle of radius 35.0 m. If the coefficient of static fric- tion between crate and truck is 0.600, how fast can the truck be moving without the crate sliding?
