A majorette takes two batons and fastens them together in the middle at right angles to make an x shape. Each baton was 0.80 m long and each ball on the end is 0.20 kg. (Ignore the mass of the rods.) What is the moment of inertia if the arrangement is spun around an axis through the center perpendicular to both rods

The system essentially consists of 4 balls of. 2 kg each at. 8 / 2 m from center

Total moment of inertia of the 4 balls

4 x m r²

= 4 x. 2 x. 4²

=.128 kg m².
