Homework Statement
A thin, uniform 3.70- bar, 90.0 long, has very small 2.50- balls glued on at either end (the figure ). 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
Find the angular velocity of the bar just as it swings through its vertical position.
