## Homework Statement

We have experimented on rolling cylinders and have gotten the function for a rolling cylinder but have gotten a strange constant from experiment.

## Homework Equations

[tex]t = 2\sqrt{\frac{l}{g}(1+\frac{r}{R})\frac{1}{\sin{\theta}}}-0.5[/tex]

## The Attempt at a Solution

Is this constant wrong? Which we think it is. We got it from linearisation from matlab. It doesn't make sense and probably is the fault of experiment. Any thoughts?
