flat unbanked curve on a highway has a radius of 250 m. What is the maximum speed in m / s a car can turn around the curve without sliding if the coefficient of static friction between the tire and the road is 0.95?

A car rounds a level turn with an 85-m radius. Suppose it is an icy day when the coefficients of the static and kinetic friction between the car's tires and the road at 0.15 and 0.13, respectively. What is the largest speed the car can take the turn without slipping?

Bob is driving with constant speed in a curved path with radius r = 50 m. If the coefficient of static friction between his tires and the road is 0.5, what is the maximum speed he can have without skidding?

Friction provides the force needed for a car to travel around a flat, circular race track. What is the maximum speed at which a car can safely travel if the radius of the track is 80 m and the coefficient of friction is 0.4?

A curve in a stretch of highway has radius 512 m. The road is unbanked. The coefficient of static friction between the tires and road is 0.600. a. What is the maximum safe speed that a car can travel around the curve without skidding?  answer in m/s b. Which of the following is the correct free-body diagram of the car when it enters the curve at a speed greater than the maximum safe speed? (OPTIONS ATTACHED) c. When the car enters the curve at a speed greater than the maximum safe speed (speed at which the car won’t skid), which of the following statements are correct?  The static frictional force is not large enough to keep the car in a circular path. The car skids toward the outside of the curve. The car skids toward the inside of the curve. The static frictional force is large enough to keep the car in a circular path.

A car going around an unbanked curve is found to be able to take the curve with maximum speed “v.” You would like to triple the maximum speed the car can take the curve. To do this, you could:     triple the coefficient of friction between the car and the road;     decrease the radius of the road by a factor of three     increase the radius of the road by a factor of nine     decrease the coefficient of friction between the car and the road by a factor of nine;

Problem 6: A car with mass m = 1000 kg is traveling around a circular curve of radius r = 840 m when it begins to rain. The coefficients of static friction between the road and tires is ug = 0.63 when dry and uw = 0.29 when wet.

If 0.5 kg-ball is swung in the horizontal direction, what force must a person exert on a string attached to make it revolve in a horizontal circle of radius 2.5 m. The ball makes 420 rpm.

If the curve on the road has a bank angle of 18 degrees and the radius of curvature is 225m. a) what is the maximum speed you can go if the coefficient of friction between the tires and the road is 0.3? Your car is 1500kg. b)What is the minimum speed you can go without sliding?

A car enters a 311-m radius horizontal curve on a rainy day when the coefficient of static friction between its tires and the road is 0.68. What is the maximum speed at which the car can travel around this curve without sliding in m/s? Answer:
