A car traveling at 18m/s goes around a flat turn with a radius of 40m without skidding. What is the minimum possible coefficient of friction for this road?
A car travels around an unbanked 60 m radius curve without skidding, If the coefficient of friction between the tires and road is 0.4, what is the car's maximum speed? 55 kph 47 43 kph 76 kph 62 kph
a car goes around an unbanked (flat) curve with a radius of 75 m. The cars tires are worn down so the coefficient of friction between the tired and asphalt is 0.60. What is the magnitude of the cars maximum possible velocity around the curve?
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...
When you take your 1200-kg car out for a spin, you go around a comer of radius 50 m with a speed of 20 m/s. The coefficient of static friction between the car and the road is 0.88. Assuming your car doesn't skid, what is the force exerted on it by static friction? Express your answer using two significant figures.
A car travels at constant speed around a corner. The cars speed is 35 m/s and the radius of the circle is 0.25 km. The coefficient of static friction between the tires and the road is 0.7. What is the frictional force needed for the car to make the turn? What is the maximum force the static friction can produce? Does the car stay on the road? The car is in motion so why is the static friction important?
3. A car is driving at a speed of 20 m/sec on a circular horizontal flat (unbanked) road of radius 200 m. (a) What minimum coefficient of static friction will permit the car to follow the circular path without skidding? (b) If the road had a radius of 32 m, what is the maximum speed of the car without skidding? (c) If the road was banked (not flat), could the car go faster? Explain your answer Possibly (but not necessarily)...
a 1500 kg car goes around a curve of radius 190 m. There is rain on the road dropping the coefficient of friction to 0.33. Find the speed that the car should go around the curve.
A curve of radius 160 m is banked at an angle of 10. An 800-kg car moves the curve at 85 km/h without skidding. Neglect the effects of air drag. Find (a) The frictional force exerted by the pavement on the tires (b) The minimum coefficient of static friction between the pavement and the tires.
A car travels at a speed of 21 m/s around a curve of 27 m. m = 1500 kg (i) What is the net centripetal force needed to keep the car from skidding sideways? (ii) Were there no friction between the car’s tires and the road, what centripetal force would be provided just by banking the road at 29o? (iii) Now, suppose a friction force is also present and prevents the car from skidding. Calculate the magnitude of the normal...
