A uniform rod of length L is free to pivot around an axis through its upper end. If it is released from rest when horizontal, at what speed is the lower end moving at its lowest point? For the moment of inertia of a rod about an axis passing thorugh one of its end use (1/3)mL2 where m is the mass and L the length of the rod. [Hint: The gravitational potential energy change is determined by the change in height of the center of gravity.]
