Friction Formulas: Fn, Ff & Mu w/ D, T, A, Vi & Ramp Angle
I think I might have fixed my problem as ay=Fgy=0 so that changes things. Also it's an inclined plane question.- Lobber

Friction Formulas: Fn, Ff & Mu w/ D, T, A, Vi & Ramp Angle
D=1.83M T=1.06S A=3.257m/s/s angle/theta is 54 degrees Vi=0 M=0.5kg Friction force? Normal force? Mu? Formula#1 (didn't work...) Ff: (cos theta A)*M=Max=Fx Fx=Ffx-Fgx Fgx=(sin theta)Mg. Fn: Ma(sin theta) = May May=Fy=Fny-Fgy Fgy=M*(cos theta)g Ff/Fn=mu Formula2 Fx=Max ax=a(cos theta) Fy=May...- Lobber

Friction Formulas: Fn, Ff & Mu w/ D, T, A, Vi & Ramp Angle
Homework Statement What is the formula for: Fn, Ff, and mu when you have a object sliding down a ramp. Variable know are D, T, A, Vi, and the angle of the ramp above the horrizon. The Attempt at a Solution I've tried a few that ended up being quite long and all wrong...- Lobber

Measuring the coefficient of friction
I don't know don't have the answers for it... the answer I did get for your formula was mu=.811- Lobber

Measuring the coefficient of friction
Well the main purpose of the assignment to to get the coefficient but we also need the Ff and Fn and how we got to all 3 in the most basic of steps... Sign and I thought I finally had my formula...- Lobber

Measuring the coefficient of friction
What is the coefficient of friction for a metal mass sliding down a wooden slope? Mass=0.50kg Slope distance=1.83m Angle=54 Degrees Time=1.06 s Vi=0m/s g=9.81m/s/s For this question we had to write out a formula and find mu. I first found acceleration to be 3.257m/s/s, Friction force to be...- Lobber
