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? When a car goes around a banked circular curve at the proper speed for the banking angle, what force cause it to follow the circular path? gravity the...

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

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....

You are advisor to a race car team. Their car is going around an unbanked race track that has a variety of curves in it. The coefficient of friction of the tires is 0.4, meaning that 0.4 mg is the maximum force the tires can exert on the car. They ask you to tell them what is the maximum speed they should drive the car around the sharpest curve which has a nearly circular arc with a radius of curvature...

You want to design a circular racetrack of radius r such that cars of mass m can go around the track at speed u without the aid of friction or other forces other than the perpendicular contact force from the track surface. Find an expression for the required banking angle 9 of the track, measured from the horizontal. Suppose the racecars actually round the track at a speed W> u. What additional radial force is required to keep the cars...
