I have been wrestling with this problem for a few days and it is really frustrating me. The image below shows a bar of length(adsbygoogle = window.adsbygoogle || []).push({}); lwhose endpoints are constrained to move along the lines shown. PointAmoves at a constant velocity to the right and I want to find the angle theta as a function ofx._{A}

I dusted off my dynamics textbook, and there are many examples of this set up in the kinematics chapter, but the only analytical solution shown has the angular acceleration of the bar as a function oftheta,alphaandx._{A}
