SUMMARY

The discussion focuses on calculating the coefficient of friction for an object on an inclined plane and determining the maximum acceleration for a runner using Nike shoes with a coefficient of friction of µ=0.3. The angle at which the object begins to slide is given as 35 degrees. Key equations mentioned include fk = µkFn and fsmax = µsFn, which are essential for solving these problems. Participants emphasize the importance of understanding the normal force (Fn) at the specified angle to proceed with the calculations.

PREREQUISITES
  • Understanding of basic physics concepts, particularly friction and inclined planes.
  • Familiarity with the equations of motion and forces, specifically fk = µkFn and fsmax = µsFn.
  • Knowledge of how to calculate normal force in relation to angles.
  • Basic algebra skills for manipulating equations and solving for unknowns.
NEXT STEPS
  • Learn how to calculate normal force on an inclined plane.
  • Explore the relationship between angle of inclination and coefficient of friction.
  • Study the dynamics of motion to understand maximum acceleration in friction scenarios.
  • Investigate real-world applications of friction coefficients in sports equipment design.
USEFUL FOR

Students studying physics, educators teaching mechanics, and sports scientists interested in the effects of friction on athletic performance.

Homework Statement


An object rests on an inclined plane. One end of the plane is lifted until the object begins to slide. The angle at which the object begins to slide is 35 degrees. What is the Coefficient of Friction

Homework Equations


fk = µkFn
fsmax=µsFn

The Attempt at a Solution


Honestly, I don't even know where to begin on this one. Only one variable is given, in what looks (to me) to be a problem where more than one variable is called for to be solved.
Similarly...

Homework Statement


Nike uses a sole for a line of shoes that has a coefficient of friction, µ=.3. Find the maximum acceleration that a runner using these shoes can have.

Hi bassboy! Welcome to PF! :smile:

Hint: What is the normal force, Fn, when the angle is 35º? :wink:

Show us what you've tried, and where you're stuck, and then we'll know how to help. :smile:
