Two small objects of equal weight are attached to the ends of a thin weightless bar that spins about an axis perpendicular to the bar at its center. Each mass is a distance d from the axis of rotation. The system spins at a rate so that its kinetic energy is K.
If both masses are now moved closer in so that each is d/6.00 from the rotation axis, while the angular velocity does not change, the kinetic energy of the system will be?
