An arrow of length L traveling with speed up strikes a smooth hard wall obliquely as shown below.

End A doesn't penetrate, but slides downward along the wall without friction or rebound. Find

the angular velocity of the arrow after impact. Treat the arrow as a slender bar. Since the impact

force is so much more than the gravity force, you may ignore gravity.
