    An engineer must design a curved exit ramp for a highway in such a way that a car, exiting at the posted speed limit of 17.88 m/s (40 mi/hr), does not depend on friction to round the curve without skidding. The radius of the curve is 230 m. At what angle with respect to the horizontal must the curve be banked (in degrees)?

    Help please I don't no how to do these The curved section of a horizontal highway is a circular unbanked areof radius 760 m. If the coefficient of statiefriction between this roadway and typical tires is 0.40m, what would be the maximum safe driving speed for this horizontal curved section of highway?

    On a highway curve with radius 30 m, the maximum force of static friction (centripetal force) that can act on a 1,273-kg car going around the curve is 9,127 N. What speed limit should be posted for the curve so that cars can negotiate it safely?

    A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...

    A car is driving around a flat highway curve that has a radius of 100 meters. The coefficient of friction between the wheels and pavement is 0.8. Please show work! A) Draw a force diagram for the car. What is the force responsible for the centripetal acceleration of the car? B) What is the fastest speed the car can drive around the curve?

    On a highway curve with a radius of 46 meters, the maximum force of static friction that can act on a 1,200 kg car going around the curve is 7,500 Newtons. What speed limit should be posted for the curve so that cars can negotiate it safely? [Express the answer in m/s and mph] 17.322 m/s, 38.975 mph 16.956 m/s, 38.151 mph 16.956 m/s, 37.033 mph 16.459 m/s, 37.033 mph 16.956 m/s, 38.975 mph

    Highway curves are "banked" inward, so gravity assists the car's traction. Suppose another highway curve has a radius of curvature of 500m. It is banked so that traffic moving at 30m/s can travel around the curve without needing any help from friction. a) Draw a force diagram for a car traveling around this curve at a constant speed. Draw the diagram so that you are looking at the rear of the car. Do not tilt your coordinate axes for this...

    In order to design safe high-speed entrance and exit ramps, highway engineers need to know about the force of friction and the maximum speeds that motorists can navigate these ramps. Suppose the coefficients of friction between rubber tires and asphalt are µs = 0.35 for static friction and µk = 0.25 for kinetic friction. You are the highway engineer charged with construction of a new freeway exit ramp. (a) Make a free-body diagram showing all of the forces acting on...

    I need help with this question! 1. A car turning in a circle is acceleratring in the centripetal direction, even if the speed is constant. This centripetal acceleration is the cause of a radially inward directed net force. On a level road this net force is the friction force acting from the road on the tires. You already looked at examples for this. On racetracks and also highway turns the reliance on friction can be reduced by "banking" the road....
