The problem
I am currently trying to right a lab report on a experiment trying to find a flywheels moment of inertia. In the lab we had a fly wheel connected to a mass on a string, and measured the position of a point on the wheel as the mass was accelerating downwards. The data was analysed with a program that generated a graph and has the line of fit that I came up with.

X position vs time ---------------------------------------- -------------- Y position vs time
My problem is that I don't know how the equations relate to physical properties. For instance, the x position graph uses the equation "f(z) = -0.064 + 0.061 sin (-2.79 + 0.390088z2)" but I don't know how these numbers actually related to any physical properties.
To find the moment of inertia I will use the equations mgh = Iω2/2 to find the moment of inertia.
I really don't know where to start.
