The rod AB is confined to move along the inclined planes at A and B. If point A has an acceleration of 3 m/s2 and velocity of 2 m/s, both directed down the plane at the instant the rod becomes horizontal, determine the angular acceleration of the rod at this instant.

Question

Do not solve for angular acceleration. 

Why is  the angular velocity positive 0.283? i could only get -0.283. May i know where i went wrong? My working is shown in the 2nd pic

Solve it without using the instanenous  center of zero velocity.
