A merry-g-round (I=1/2MR^2) of mas 250kg and radius 3m has been spun so that is has an angular velocity of 15 rad/s. Piper and Benjamin leap onto the merry-go-round and land at distnaces of 1.5m and 2.5m respectively from the center. Piper's mass is 40kg and Benjamin's mass is 75kg. Treating them as point masses (I=MR^2), what is the final angular velocity of the merry-go-round?
I=MR^2
