Answer 6

the answer is 2/9. but I don't understand the work behind it. they did
(1/3m)(Mx1 + m(x1+ l/4) + m(x1+l/4+l/2). with x1 being the amount of the book ON the table.

@Hero

Answer 8

sorry cant help

Answer 9

1/3m( mx1+m(x1+1/4)+m(x1+1/4+1/2)

x1=-1/3, 1/2-1/3= 1/6

1/6 bottom book can over hang

Answer 10

why is the second value x1 + 1/4 though?

Answer 11

I would imagine it'd be x1- l/4. right? cause that's the part of the book that's on the table?

Answer 12

Center of mass of each book at its center
