A girl weighing 60 KG is at the rim of a merry-go-round. The radius of the merry-go-round is 2 M. Her speed on the rim is 2 radians a second. The merry-go-round weighs 100KG.(adsbygoogle = window.adsbygoogle || []).push({});

I of student=MR2 (thats MR squared)

I of merry-go-round=1/2MR2 (thats MR squared also)

What is her speed if she moves to be .5 M from the center of the merry-go-round. I know the answer is 4.09 radian, but I cannot figure out how to get that, thanks a lot for the help
