Ricky Bobby used to be the best there is at car racing. But then he had an accident and has been scared to go fast ever since. Ricky Bobby goes around a banked curve on a race track at less than ideal speed, so that a friction force between the road and his car tires must keep him from sliding down the track. The curve is banked at an angle of 21° and has a radius of curvature of 155 m. The coefficient of friction between the road and his tires is 0.80 and he takes the curve at a timid 45. Does Ricky slide down the т track or does friction keep him at the same height on the curve? (Hint: Solve this problem as if the car does not slide. Comparing the magnitudes of the kinetic friction force and the component of weight parallel to the track will tell you if it slides. This requires MUCH algebra.)

Engineers are designing a curved section of a highway to fit into a specific area. The curve has radius 121 m and is banked at an angle such that a car can travel around the curve at 28.7 m/s and stay on the road without the aid of a frictional force. Calculate the required banking angle (as measured above the horizontal). 0 =
Astronauts in the International Space Station must work out every day to counteract the effects of weightlessness. Researchers have investigated if riding a stationary bicycle while experiencing artificial gravity from a rotating platform gives any additional cardiovascular benefit. What frequency of rotation, in rpm, is required to give an acceleration of 1.4g to an astronaut’s feet, if her feet are 1.1 m from the platform’s rotational axis?
The Texas Motor Speedway is an oval racing track with curves of radius 229 m that are banked at an angle of 24.0°. The size of the track allows for race cars to achieve speeds in excess of 400 km/h. An unintended consequence of the banked curves and high speeds is that race car drivers experience excessive G forces, especially in the "vertical" direction (with respect to their body position), causing dizziness and loss of consciousness. (a) A daring driver, pushing his car to the limit, experiences 4.67g of centripetal acceleration during one banking maneuver. What is the speed of his car during the maneuver? (Give your answer in km/h.) km/h (b) If the driver is seated so that during the banking maneuver his upper body is aligned with the direction normal to the banked curve, what is the magnitude of the component of the centripetal acceleration along the driver's upper body? (Give your answer in terms of g.) a delete
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.

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 puck is sliding around a circular track that is banked at an angle ϕ with respect to the horizontal such that no friction between the puck and the track is required to keep the puck from slipping up or down the track. If the puck is moving at a speed 34.1 m/s and the radius of the track is 401 m, determine ϕ in degrees.

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 road with a radius of 75.0 m is banked so that a car can navigate the curve at a speed of 16.8 m/s without any friction. When a car is going 36.8 m/s on this curve, what minimum coefficient of static friction is needed if the car is to navigate the curve without slipping?
