Maximum speed on a banked road to avoid skid is given by:
v = sqrt(gR tan(th)
= sqrt (9.82*52*tan18)
= 12.87 m/s
= 12.87431689 * 3.6 kph
= 46.346 kph
5. An automobile goes around a slippery curve of radius 52 m. If the road is...
A car goes around a curve on a road that is banked at an angle of 33.5 degree. Even though the road is slick, the car will stay on the road without any friction between its tires and the road when its speed is 23.0 m/s. Part A What is the radius of the curve?
A curve with a 130 m radius on a level road is banked at the correct angle for a speed of 20 m/s. If an automobile rounds this curve at 30 m/s, what is the minimum coefficient of static friction between tires and road needed to prevent skidding?
A section of U.S. highway with a posted speed limit of 70.0 mph (113 kph) has a curve of radius 1,170 ft (357 m). At what angle should the curve be banked so that cars travelling at the speed limit have no tendency to skid sideways? Bank angle: ______________° What if the road were on Mars? (Martian surface gravity is 3.71 m/s².) Assume the same coefficient of friction for a dusty road on Mars as for a wet road on...
A car travels around an unbanked 60 m radius curve without skidding, If the coefficient of friction between the tires and road is 0.4, what is the car's maximum speed? 55 kph 47 43 kph 76 kph 62 kph
5. (10 pts): A car of mass M goes around an icy banked turn of radius t at a speed v. If there is no frictional force and the car takes the turn without skidding, at what angle 0 is the turn banked?
A curve on a road has a radius of curvature of 500.0m and is banked at an angle of 10.00 degrees, if a 1700.0Kg car is traveling at a speed of 27.0m/s around the curve, what is the magnitude and direction of the static frictional force needed to keep the car around the curve at this speed?
a 1500 kg car goes around a curve of radius 190 m. There is rain on the road dropping the coefficient of friction to 0.33. Find the speed that the car should go around the curve.
please answer 2 questions pleaeeee #o: A 600-kg car traveling at 24.5 m/s is going around a curve having a radius of 120 m that is banked at an angle of 20°. (a) Draw a free body diagram (b) What is the reaction of the road on the car? (c) Is the curve properly banked for the car's speed? (d) What is the minimum coefficient of static friction required between the road and the car's tires so the car does...
Two banked curves have the same radius. Curve A is banked at 10.9 °, and curve B is banked at an angle of 18.8 °. A car can travel around curve A without relying on friction at a speed of 17.1 m/s. At what speed can this car travel around curve B without relying on friction?
