Speed & Velocity & Friction Force ?

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum speed a car can maintain while navigating a horizontal curve with a radius of 25 meters, given a coefficient of friction (μ) of 0.8. The key equation used is the relationship between frictional force and centripetal force, expressed as F_friction = F_centripetal. By applying the formula F = μN, where N is the normal force, participants aim to derive the maximum speed using the provided parameters.

PREREQUISITES
  • Understanding of centripetal force and its relationship to circular motion
  • Familiarity with the concept of friction and the coefficient of friction
  • Basic algebra for manipulating equations
  • Knowledge of Newton's laws of motion
NEXT STEPS

Speed & Velocity & Friction Force ?

Homework Statement


With What Max.Speed? a Car can move in horizontal curve with radius r=25m,
if the coefficient of friction is u=0,8


Homework Equations



ƒ = μN S= D/T

The Attempt at a Solution



i tryed bunch of garbages so as i don't kno which is right:S

The frictional force provides the centripetal force.

So Frictional force=centripetal force.
