Friction, speed, and radius of a curve?

Click For Summary
SUMMARY

The discussion focuses on calculating the speed at which a car will begin to slide while rounding a level curve with a radius of 39.3 meters, given a coefficient of static friction of 0.789. The relevant equations include the formula for centripetal acceleration, a = v²/r, and the maximum static frictional force, f(s,max) = μ(s) * F(n). The frictional force must equal the centripetal force for the car to remain on the curve without sliding.

PREREQUISITES
  • Understanding of uniform circular motion and centripetal acceleration
  • Knowledge of static friction and its coefficient
  • Familiarity with Newton's laws of motion
  • Basic algebra for solving equations
NEXT STEPS
  • Calculate the maximum speed using the equation v = sqrt(μ(s) * g * r)
  • Explore the effects of varying the radius on the required speed
  • Investigate the role of negative lift in vehicle dynamics
  • Learn about frictional forces in different road conditions
USEFUL FOR

Students studying physics, automotive engineers, and anyone interested in vehicle dynamics and safety on curves.

Homework Statement



Suppose the coefficient of static friction between the road and the tires on a car is 0.789 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 39.3 m radius?

Homework Equations



i know the equation for uniform circular motion is a=(v^2)/r
verge of sliding means f(s,max)=mu(s)*F(n)

The Attempt at a Solution



and seriously, I have no idea where to start.

Well shouldn't the frictional force provide the centripetal force required?
