Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_153

6/153 The slender bar of mass $m$ and length $l$ is released from rest in the horizontal position shown. If point $A$ of the bar becomes attached to the pivot at $B$ upon impact, determine the angular velocity $\omega$ of the bar immediately after impact in terms of the distance $x$. Evaluate your expression for $x = 0$, $l/2$, and $l$.
