A thin uniform rod of mass M and length L is positioned vertically above an anchored frictionless pivot point and then allowed to fall to the ground. With what speed does the free end of the rod strike the ground?(adsbygoogle = window.adsbygoogle || []).push({});

My answer is off by sqrt(2) from the correct answer, sqrt(3gL), and I don't understand why. Please help!!
