Determining Coefficient of Kinetic Friction (mew)

Click For Summary
SUMMARY

The discussion focuses on calculating the coefficient of kinetic friction (µ) for a box sliding down a 31-degree ramp with an acceleration of 1.42 m/s². To determine µ, participants emphasize the importance of drawing a Free Body Diagram (FBD) to identify the forces acting on the box, including weight, normal force, and frictional force. The application of Newton's laws in both the x and y directions is crucial for solving the problem effectively. The discussion highlights the necessity of understanding inclined planes to approach the solution correctly.

PREREQUISITES
  • Understanding of Free Body Diagrams (FBD)

Homework Statement


A box slides down a 31 degree ramp with an acceleration of 1.42 m/s squared. determine the coefficient of kinetic friction (mew) between the box and the ramp.


Homework Equations


F=ma Fnet=ma Fn(µ)=Ff


The Attempt at a Solution


Many attempts on paper but unable to show on this.

Please show one of your attempts so we may better assist. You need to draw a FBD of the box identifying the weight, normal, and friction forces acting on it,,,,,,,look up 'inclined planes'...and for simplicity choose the x-axis as parallel to the plane and the y-axis as perpendicular to the plane..and Apply Newton's laws in the x and y directions.
