I have managed to rearrange an equation give to me to make I (moment of inertia) the subject. I am now having problems working out the values for parts of it.(adsbygoogle = window.adsbygoogle || []).push({});

I = moment of inertia

m = mass

g = gravity

h = height

v = translational speed of the mass falling

Tf = work done against friction

theta = angle through which flywheel rotates in radians

w = rotational speed of the flywheel

The equation is I = (1/2mgh - mv^2 - Tf * theta) / w^2

I am finding it hard to work out a value for v and w. is 'the translational speed of mass falling (v)' is that just a fancy way of saying velocity?

I am unsure of how to find a value for w

Hope this makes sense

Thanks
