Homework Statement
So I need to find the values for local acceleration and frictional force due to a pulley system using the equation below. After graphing acceleration for various ∆mass vs acceleration using Excel, I get the following equation:
y = 0.0144x - 0.0875
I don't understand what the slope and y intercept in this equation represent though, how can I use them to find the 'local acceleration and frictional force'?
Homework Equations
a = (∆m/TOTAL MASS)g - (f/TOTAL MASS)
where f = frictional force
The Attempt at a Solution
I think I'm supposed to get the gravity constant from the linear equation, but not sure how. Obviously it's not 0.0144.
