A small 13.0-g bug stands at one end of a thin uniform bar that is initially at rest on a smooth horizontal table. The other end of the bar pivots about a nail driven into the table and can rotate freely, without friction. The bar has mass 65.0 g and is 110 cm in length. The bug jumps off in the horizontal direction, perpendicular to the bar, with a speed of 15.0 cm/s relative to the table. What is the angular speed of the bar when the insect leaps off?
