Question 1039895
In question # 103894, we found that while Jessica was spinning at a constant rpm,
and the 2 kg masses were traveling in circles at 1.1 m/s,
the combined linear momentum of those masses was
{{{L=r*m*v[1]=2*(0.6m)*(2kg)*("1.1 m / s")=2.64}}}{{{m^2*kg/s
}}} .
When the masses get to {{{r=0.15m}}} distance from the center of rotation,
if they have the same angular moment,
they will have a much greater tangential velocity, {{{v[2]}}} ,
with {{{L=2*(0.15m)*(2kg)*v[2]=2.64}}}{{{m^2*kg/s}}} .
So, those masses will be circling at a tangential speed
{{{v[2]=2.64/(2*0.15*2)}}}{{{"m / s"=highlight(4.4)}}}{{{"m / s"}}} .
 
NOTE:
That might be realistic, because Jessica is a very small , slender girl,
so her small tightly centered body mass, does not contribute much to the angular momentum,
and those spindly arms did not have that much momentum (even when fully stretched)
compared to the momentum of the 2 kg masses held so far from the axis of rotation.
