Question
![A thin, uniform 3.80 kg bar, 90.0 cm long, has very small 2.50 kg balls glued on at either end (Figure 1). It is
supported horizontally by a thin, horizontal, frictionless axle passing through its center and perpendicular to the
bar. Suddenly the right-hand ball becomes detached and falls off, but the other ball remains glued to the bar.
