Homework Statement
You place a piece of wood onto a 227cm long piece of metal on a 25 angle. The [tex]\mu[/tex]=.34 How long does it take for the piece of wood to reach the bottom of the metal?
Homework Equations
[tex]\Delta[/tex]X=227
Vi=0
a=?
t=?
[tex]\Delta[/tex]X=ViT+.5at^2
227=.5at^2
a=Fnet/m
[tex]\mu[/tex]=Ff/Fn
The Attempt at a Solution
I have 2 pages of work for this problem and it's obvious to me that I'm missing something crucial. I tried this problem a few times, the first time I calculated the wrong [tex]\mu[/tex] and the second time I have no idea what happened
I can't reproduce my free body diagram for you but I can tell you what I broke the components down into:
Fg=y'/sin25
Fg=x'/cos25
