Question: A person holds a 4-kg weight in each hand with arms outstretched while standing at rest on a lightweight platform that is free to turn about a vertical axis. Other people then set the person turning at a rate of one turn per 7.2 s. The person then lowers the weights until they are alongside the person's legs. At this point, the person is spinning once every 1.2 s.

Question 1: Estimate the person's moment of inertia?

I need help to determine the person's moment of inertia.
