A small 11.0 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 70.0 g and is 90 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.
