L = r x p = Iω

this is the only equation i think i need for this problem

As far as i can tell all i would need to do is...

since R is unknown but will be a constant through out the whole problem, i give it a value of 1 for simplicity sake.

the momentum of the turntable before would be, L = (7.5 x 1^2) x 1.4

L= 10.5

since momentum as to be conserved in this problem the end momentum should also be 10.5

10.5 = [(7.5 x 1^2) + (7.1 x 1^2)] x ω

10.5 = 14.6 x ω

10.5/14.6 = ω

.719 = ω

and since this is a online assignment i can try and answer as many times until i get it correct, but i can't think of where i might be going wrong cause it says i have the wrong answer.

I don't need the problem worked out for me per say...just maybe hint at the error or explain where I am going wrong, and thank you for any help
