A bug of mass 10.0 g 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 50.0g and is 100 cm in length. The bug jumps off in the horizontal direction, perpendicular to the bar, with a 20.0 cm/s relative to the table. a) What is the angular speed of the bar just after the bug leaps? b) What is the total kinetic energy of the system just after the bug leaps? c) Where does this energy come from?

2. Relevant equations

Ke= 1/2 MVcm^2

3. The attempt at a solution

First I want to say thanks, you all have been a big help to me with the questions I have posed in the past... I don't always say it but thank you.

My problem is trying to set it up, I tried to draw the picture and can't visualize the orientation of the system. I can't seem to figure out how the bar rotates if it is horizontal then how can the bug jump off in the horizontal direction perpendicular to the bar. Any thoughts to help me put this in perspective?
