SUMMARY

The maximum speed at which a car can travel around a circular path without skidding is determined by the radius of the path and the coefficient of static friction. In this discussion, a car with a radius of 20.0 m and a static friction coefficient of 0.72 was analyzed. The correct maximum speed, calculated using the formula v = sqrt(μ * g * r), is 12 m/s, not 18 m/s as initially suggested. This conclusion is based on the assumption of gravitational acceleration (g) being 10 m/s².

PREREQUISITES
  • Understanding of circular motion dynamics
  • Knowledge of static friction coefficients
  • Familiarity with basic physics equations, particularly v = sqrt(μ * g * r)
  • Ability to perform unit conversions and calculations
NEXT STEPS
  • Study the physics of circular motion and centripetal force
  • Learn about the role of friction in vehicle dynamics
  • Explore the implications of varying coefficients of friction on vehicle performance
  • Investigate real-world applications of these principles in automotive engineering
USEFUL FOR

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

Check a physics "Q".

For this question i got 18m/s is this correct?
A car travels in a circular path of radius 20.0 m. If the coefficient of static friction is 0.72, find the maximum speed at which the car can travel around the curve without skidding. Assuming g=10m/s^2.
