Question

A woman with mass of 63 kg stands at the
rim of a horizontal table having a moment of
inertia of 520 kg m2
and a radius of 1.5 m.
The turntable is initially at rest and is free
to rotate about a frictionless, vertical axis
through its center. The woman then starts
walking around the rim clockwise (as viewed
from above the system) at a constant speed of
1.3 m/s relative to the Earth.
With what angular speed does the
turntable rotate?
Answer in units of rad/s
