Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.they conserved net angular momentum since external torque = 0, but:
they found the final momentum about point C. why does that work when the question asks for angular momentum of the system at the point of collision, which is the centroid?
also i'm not sure what the expression is for the angular momentum
