Question

Three children are riding on the edge of a merry-go-round that is a disk of mass 98 kg, radius 1.7 m, and is spinning at 19 rpm. The children have masses of 21.6 kg, 27.6 kg, and 35 kg.

M = 98 kg
m₁ = 21.6 kg
m₂ = 27.6 kg
m₃ = 35 kg
r = 1.7 m
f = 19 rpm

If the child who has a mass of 27.6 kg moves to the center of the merry-go-round, what is the new magnitude of angular velocity in rpm?

f' =
