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.)

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

3. 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
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
