A thin, uniform 3.90 kg bar, 80.0 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.
Find the angular acceleration of the bar just after the ball falls off.
Express your answer in radians per second squared.
