Now, suppose that the curve is level (θ=0) and that the ice has melted, so that there is a coefficient of static friction μ between the road and the car's tires as shown in (Figure 2) . What is μmin, the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 50.0 km/hour and that the radius of the curve is 54.1 m .
the frictional force provides the necessary centripetal force
Fc = fs
m*v^2/r = u*m*g
v^2/r = u*g
v = 50 km/h = 50*(5/18) = 14 m/s
(14^2)/54.1 = u*9.8
u = 0.369 <<---------answer

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 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 flat (unbanked) curve on a highway has a radius of 250 m. A car successfully rounds the curve at a speed of 35 m/s but is on the verge of skidding out. a. Draw free body diagram of the car. b. If the coefficient of static friction between the car's tires and the road surface were reduced by a factor of 2, with what maximum speed could the car round the curve without slipping? c. Suppose the coefficient of friction were increased...
