As you are riding in a 1650-kg car, you approach a N7M.8 hairpin curve in the road whose radius is 50 m. The road- bed is banked inward at an angle of 10° (a) Suppose the road is very icy, so that the coefficient of static friction is essentially zero. What is the maximum speed at which you can go around the curve? (b) Now suppose the road is dry and that the static friction coefficient between the tires and the asphalt road is 0.6. What is the maximum speed at which you can safely go around the curve?

A. Given that a racecar with a mass of 795.0 kg is going through an unbanked curve of a constant radius of 122.0 meters, with racing tires with a static friction coefficient of 0.85 with the race track, what is the maximum speed that the racecar can take with the curve and not slide, assuming the car generates no negative lift? B. How much frictional force does the car need to generate to follow the curve without losing control or slipping? C. Would the speed of the racecar change if the experiment was conducted on an alien planet with a gravity of 8 m/s^2?

A race track curve has a radius of 90 m and is banked at an angle of 15°. the coefficient of static friction between the tires and the roadway is 0.4. a race car with a mass of 1200 kg rounds the curve with a maximum speed to avoid skidding. What’s the normal force on the car as it rounds the curve (exerted by road), the radial acceleration, and speed?

You are driving on a circular ramp of radius 72.0 m on an icy January day. The ice-covered ramp is banked at a 23.0° angle, and you anticipate that the ramp is not going to provide any significant friction to help keep your car on the road. (a) What must your speed be so that your car does not slide off the road? (b) What are the direction and magnitude of the net force acting on you at that point? Your mass is 72.0 kg

A banked circular highway curve is designed for traffic moving at 60 km/h. The radius of the curve is 200 m. Traffic is moving along the highway at 40 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.)

If the curve on the road has a bank angle of 18 degrees and the radius of curvature is 225m. a) what is the maximum speed you can go if the coefficient of friction between the tires and the road is 0.3? Your car is 1500kg. b)What is the minimum speed you can go without sliding?

A car enters a 311-m radius horizontal curve on a rainy day when the coefficient of static friction between its tires and the road is 0.68. What is the maximum speed at which the car can travel around this curve without sliding in m/s? Answer:

Two banked curves have the same radius. Curve A is banked at 13.9 °, and curve B is banked at an angle of 18.1 °. A car can travel around curve A without relying on friction at a speed of 13.7 m/s. At what speed can this car travel around curve B without relying on friction?

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
