a stack of seven identical aluminum blocks, each of length l = 17.1 cm
and thickness d = 1.8 cm, stacked on a table.
(a) How far to the right of the edge of the table is it possible for the right edge of the top (seventh) block to extend?
(b) What is the minimum height of a stack of these blocks for which the left edge of the top block is to the right of the right edge of the table?
I know who you are, and this is unacceptable! See me Wednesday after class.
