A car of mass M = 800 kg traveling at 55.0 km/hour enters a banked turn covered with ice. The road is banked at an angle ?, and there is no friction between the road and the car's tires as shown in(Figure 1) . Use g = 9.80 m/s2 throughout this problem. Now, suppose that the curve is level (?=0) and that the ice has melted, so that there is a coefficient of static friction ? between the road and...

No.4] 7.1 Show (from first principles) that the angle, 6, at which, the road should be banked is given by: 0 arctan 7.2 A particular banked highway curve with a radius of 200 m is designed for traffic moving at 60 km/h. On a rainy...
A highway curve of radius 68.0 m is banked at 21.4 degree so that a car traveling at 26.4 m/s (95 km/hr) will utilize both banking and friction to keep it on the curve. Determine the minimum coefficient of static friction between the tires and the road to keep the car on the road at this speed on this curve.
A curve of radius 69 m is banked for a design speed of 95 km/h. If the coefficient of static friction is 0.40 (wet pavement), at what range of speeds can a car safely make the curve? [Hint: Consider the direction of the friction force when the car goes too slow or too fast.] Express your answers using two significant figures separated by a comma. vmin, vmax =
A car of mass M = 1500 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is banked at an angle ∘, and there is no friction between the road and the car's tires as shown in (Figure 1). Use g = 9.80 m/s2 throughout this problem. What is the radius r of the turn if θ = 20.0 ∘ (assuming the car continues in uniform circular motion around the turn)?

Banked curves are designed so that the radial component of the normal force on the car rounding the curve provides the centripetal force required to execute uniform clrcular motion and safely negotlate the curve. A car rounds a banked curve with banking angle θ-27.1° and radius of curvature 157 m. (a) It the coefficient of static friction between the car's tires and the road is -0.316, what is the range ot speeds for which the car can safely negotiate the turn...
A curve that has a radius of 105 m is banked at an angle of ?=10.2∘. If a 1000 kg car navigates the curve at 65 km/h without skidding, what is the minimum coefficient of static friction ?s between the pavement and the tires?
