An object is placed 17.6 centimeter in front of a convex mirror, the image being 7.26 centimeter behind the mirror. A second object, twice as tall as the first one, is located in front of the mirror, but at a different location. The image of this second object has the equal height as the other image. Find how far in front of the mirror is second object placed?
