What is the minimum coefficient of static friction required for the car not to skid?A bobsled travels along a frictionless track. It crosses the starting line with a speed of v0=3.1 m/s. At an elevation of 21m below the starting line, it takes a turn along a flat section of track (that is not uphill or downhill). This curve is banked and has a radius of curvature of r=14 m. How many times their normal weight will a rider feel when going around this curve?A car moving at 41 km/h negotiates a 150 m -radius banked turn designed for 60 km/h .

What angle should the curve be banked at for this to happen safely?A 1500 Kg car rounds a curve of radius 69 m banked at an angle of 14 degrees. what is the magnitude of the friction force required for the car to travel at 6t8 km/h?Two banked curves have the same radius. Curve A is banked at 12.6°, and curve B is banked at an angle of 19.0%. A car can travel around curve A without relying on friction at a speed of 10.7 m/s. At what speed can this car travel around curve B without relying on friction?

Will the car skid?A 600-kg car is going around a banked curve with a radius of 110 m at a speed of 24.5 m/s. What is the appropriate banking angle so that the car stays on its path without the assistance of friction?A car goes around a curve on a road that is banked at an angle of21.5°. Even though the road is slick, the car will stay on the roadwithout any friction between its tires and the road when its speedis 19.8 m>s. What is the radius of the curve?
