63. We use Ato denote the length of the stick. Since its center of mass is A/2from either end, its initial potential energy is 12mgA, where mis its mass. Its initial kinetic energy is zero. Its final potential energy is zero, and its final kinetic energy is 122Iω,whereIis 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
