Homework Help: Physics

Posted by Brock on Tuesday, February 24, 2009 at 11:35pm.

If a 2 m tall man is looking at a plane mirror from an eye which is 20 cm from the top of his head, what is the minimum length that the mirror must be so that he can just barely see his whole body in the mirror? How far up from the ground must the mirror be placed?

I'm confused about where the source/destination of each light ray should be and how to find the distance and height of the mirror after I have drawn those rays.
