A vertical 2-meter stick is placed on the ground so that y = 0.0 m is the point on the stick in contact with the ground. A camera is at the top of the stick (at y = 2.0 m) and is aimed at a flat vertical mirror 3.0 m away. An opaque sheet is placed over the bottom of the mirror. When the camera views the reflection of the stick, the top 0.8 m of the stick can be seen (that is y = 0 m to y = 1.2 m is hidden because of the sheet). What is the height h of the sheet?
