Excellent work here gentlemen. But as a physics teacher, I feel I must bring the idea of energy transfer to the table. Assuming we can ignore the work done by non-conservative forces here (I.e. friction) then the amount of gravitational potential energy the rim transfers to the floor is given by mgh, using a mass in kilograms and a height in meters, of course.
