Suppose that the coefficient of friction between a car's tires and the road is 0.600 when the road is dry and 0.350 when the road is wet. If on a certain curve the maximum speed the car can go without slipping is 42.0 m/s when the road is dry, what is the maximum speed the car can go on the same curve without slipping when the road is wet?

Suppose that the coefficient of friction between a car's tires and the road is 0.300 when the road is wet. If the car is going at 70.0 mph on a wet road and applies the maximum braking that does not result in a skid, what distance will it take for the car to stop? (Note: 1 mile = 1.609 km).
(a) Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift (aerodynamics pushing it downwards). What speed will put the car on the verge of slipping as it rounds a level curve of 60 m radius? (b) Considering the same friction coefficient, what is the steepest slope the car could be parked on and not slide?
Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 31.6 m radius?

1) A car with mass m = 1000 kg is traveling around a circular curve of radius r = 990 m when it begins to rain. The coefficients of static friction between the road and tires is μd = 0.66 when dry and μw = 0.26 when wet. a) Write an expression for the maximum magnitude of the force of static friction Ff acting on the car if μs is the coefficient of friction. b) What is the maximum tangential...
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...
Car A uses tires for which the coefficient of static friction is 0.330 on a particular unbanked curve. The maximum speed at which the car can negotiate this curve is 17.0 m/s. Car B uses tires for which the coefficient of static friction is 0.632 on the same curve. What is the maximum speed at which car B can negotiate the curve?
Car A uses tires for which the coefficient of static friction is 1.1 on a particular unbanked curve. The maximum speed at which the car can negotiate this curve is 20 m/s. Car B uses tires for which the coefficient of static friction is 0.7 on the same curve. What is the maximum speed at which car B can negotiate the curve?
