The location of a person's center of gravity relative to his or her height can be found by using the arrangement shown in \(abla\) Figure \(\mathbf{8 . 3 4}\). The scales are initially adjusted to zero with the board alone.

(a) Would you expect the location of the center of gravity to be (1) midway between the scales, (2) toward the scale at the person's head, or (3) toward the scale at the person's feet? Why?

(b) Locate the center of gravity of the person relative to the horizontal dimension.

a) How many uniform, identical textbooks of width \(25.0 \mathrm{~cm}\) can be stacked on top of each other on a level surface without the stack falling over if each successive book is displaced \(3.00 \mathrm{~cm}\) in width relative to the book below it?

(b) If the books are \(5.00 \mathrm{~cm}\) thick, what will be the height of the center of mass of the stack above the level surface?
