Luc, who is 1.80 m tall and weighs 950 n, is standing at the

center of a playground merry-go-round with his arms extended,

holding a 4.0 kg dumbbell in each hand. the merry-go-round can

be modeled as a 4.0-m-diameter disk with a weight of 1500 n.

luc’s body can be modeled as a uniform 40-cm-diameter

cylinder with massless arms extending to hands that are 85 cm

from his center. the merry-go-round is coasting at a steady

35 rpm when luc brings his hands in to his chest. afterward,

what is the angular velocity, in rpm, of the merry-go-round?
