"suppose that we repeat the experiment in the video but use hand-held weights of different masses and different initial speeds. in each of the cases below, the demonstrator starts with her arms extended (rotating at angular speed ω0) and then pulls her arms in (rotating at angular speed ωf). rank the cases below based on their final angular speed ωf (that is, when the demonstrator’s arms are pulled in), from slowest to fastest. since most of the mass of the demonstrator sits near the axis of rotation, ignore her mass for this question."
