When a 5.5 cm long pencil is arranged perpendicular to a convex mirror's optical axis at a distance of 29 cm from the mirror, its image is 2.8 cm tall. (a) What is the mirror's focal length (include sign if negative)? (b) How tall is the pencil's image if the pencil is moved to a distance of 49 cm from the mirror( include the sign negative also)?
