Alright, I know I have this stuff somewhere at school, but unfortunately, I can't leave it till tom.
A mass is at rest on a horizontal plane, and is attached by a second mass that is threaded through a pulley and is suspended in the air. What is the coefficient of friction?
The formula I've been using is
M(1)a(coefficient of friction) = M(2) (g-a)
(sorry about the horrible representation)
rearranged into this:
M(2) (g-a) = (coefficient of friction)
M(1)a
where a= acceleration
M= mass
g = gravity = 9.81
Unfortunately, upon plugging in my numbers from the experiment, I keep getting 7.5171...for the coefficient of gravity...which to me seems impossibly high!
