63. We use A to denote the length of the stick. Since its center of mass is A /2 from either end, its initial potential energy is 1 2 mg A , where m is its mass. Its initial kinetic energy is zero. Its final potential energy is zero, and its final kinetic energy is 1 2 2 I ω , where I is its rotational inertia about an axis passing through one end of the stick and is the angular velocity just before it hits the floor. Conservation of energy yields
