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 0.700. What is the maximum safe speed that a car can travel around the curve without skidding?

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.

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.

An RC car drives around in a circle of radius 1.00 m. The coefficient of static friction between the tires and the floor is 0.85; the coefficient of kinetic friction is 0.60. The mass of the car is 400 g, and its speed is 2.5 m/s. What is the maximum speed at which the car could travel and still move in the same circle ?

A hockey puck that has a mass of 0.150 kg is tied to a light string and spun in a circle of radius 1.15 m on frictionless ice. If the string breaks under a tension that exceeds 4.00 N, what is the maximum speed vmax of the puck without breaking the Umax = m/s string?

Express the following quantities in SI units:  23.4 grams = 2.34 x 10^-2  124 millimeters =  1 hour and 24 min =   0.12 centimeters =

A race track curve has a radius of 90 m and is banked at an angle of 15°. the coefficient of static friction between the tires and the roadway is 0.4. a race car with a mass of 1200 kg rounds the curve with a maximum speed to avoid skidding. What’s the normal force on the car as it rounds the curve (exerted by road), the radial acceleration, and speed?

At a circus, a stunt rider is going to do a "Loop-de-Loop". The radius of the circular part of the track is 8.13 m. The mass of the motorcycle and the rider is 318. kg. What is the minimum speed the motorcycle must have to just make it around the loop without falling?

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:

Two banked curves have the same radius. Curve A is banked at 13.9 °, and curve B is banked at an angle of 18.1 °. A car can travel around curve A without relying on friction at a speed of 13.7 m/s. At what speed can this car travel around curve B without relying on friction?
