Two banked curves have the same radius. Curve A is banked at 12.3 °, and curve B is banked at an angle of 16.4 °. A car can travel around curve A without relying on friction at a speed of 16.8 m/s. At what speed can this car travel around curve B without relying on friction?

A car negotiates an unbanked 81.7 m radius curve at 17.4 m/s.   What would the minimum coefficient of friction be needed to negotiate the curve?

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?

A car enters a horizontal, curved roadbed of radius 50.0 m. The coefficient of slatic friction between the tires and the roadbed is 0.20. What is the maximum speed with which the car can safely negotiate the unbanked curve?

A curve in a stretch of highway has radius 512 m. The road is unbanked. The coefficient of static friction between the tires and road is 0.700. What is the maximum safe speed that a car can travel around the curve without skidding?

A 693 kg car traveling at 32.8 m/s is going around a curve having a radius of 105.5 m that is banked at an angle of 26.4°. The coefficient of static friction between the car's tires and the road is 0.600. What is the magnitude of the force exerted by friction on the car?

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?

A car of mass 622 kg is driving around a curve with a circular arc of radius 20 m. If the car drives at a speed of 12 m/s, what is the minimum value of the coefficient of friction between the car's tires and the road that will keep the car on the road?

car travels at a steady 40.5 m/s around a horizontal curve of radius 251 m. What is the minimum coefficient of static friction between the road and the car's tires that will allow the car to travel at this speed without sliding?

A case of fine glassware is loaded into a truck and sits on the floor. The truck drives along a street that follows along a circle that has a radius of 30.5 meters. The street is not banked. The coefficient of static friction between case of glass and the floor of the truck is 0.570. If the truck drives too fast, the case of glassware will slip and the glass will be damaged. How fast can the truck be moving without the box sliding?
