Calculating momentum
Could one calculate momentum by using the calculation for acceleration but to extremes for example, for a 8kg 25cm radius symmetrical round object with equal weight spread and very low friction bearings, with a drag coefficiency of 0.4 and a 25cm lever on the side (the force to rotate it will be applied on the end of the lever) to rotate up to 0.000000000000000000000000000000000000000001 rpm over a time of 100,000,000,000 times 100 gazillion years ?
This is a relivant question to what I am doing so please do not think it is not relevant.
Please provide calculus with explanation of the calculus.

This is obviously your homework. We will not do your homework for you.
Please show your answer so that we can give the appropriate help.

You ask about momentum - I assume you mean angular momentum. The formula is
where I = moment of inertia, which for your disc is  and  is angular velocity, or:
 radians per second. Note that momentum has nothing to with acceleration.

The questions you ask certainly appear to be homework. If you explain why you are asking such questions it might make a difference.

In the OP's defense, he has posted a series of questions recently and this fits in with the others, all regarding construction of some sort of generator he is interested in pursuing. Plus this question is nothing like any physics homework problem I've ever seen - it's a bit confused and wrongly worded and so seems to be a simple honest question from a non-expert.

I don't think he's 39 despite his claim... I've reported him to the site admins directly for a vulgarity laced PM he sent that sounded like a 16 year old that's upset he failed his homework assignment.
