Angular momentum? please help?

A small 10.0g 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 m 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 25.0 cm/s relative to the table.What is the angular speed of the bar just after the frisky insect leaps? (in rad/s)
