1. Three children are riding on the edge of a merry-go-round that is 142 kg, has a 1.60 m radius, and is spinning at 17.3 rpm. The children have masses of 22.4, 27.5, and 38.8 kg. If the child who has a mass of 38.8 kg moves to the center of the merry-go-round, what is the new angular velocity in rpm?

The star Tau Ceti's mass is 1.6 ✕ 1030 kg, its radius is 5.5 ✕ 105 km, and it has a rotational period of approximately 34 days. If Tau Ceti should collapse into a white dwarf of radius 7.5 ✕ 103 km, what would its period (in s) be if no mass were ejected and a sphere of uniform density can model Tau Ceti both before and after?
