work on each is weight*height.
work=m*.041(1+2+3+...7)g

The gravitational potential energy is given by the equation:
Potential Energy = mass x gravity x height.
In this case, the height is the combined thickness of all the books stacked together. Since each book is 4.1 cm thick, the height of 8 books stacked will be 8 x 4.1 cm.
First, let's convert the height to meters:
Height = 8 x 4.1 cm = 32.8 cm = 0.328 m.
The mass is given as 1.8 kg.
The acceleration due to gravity, denoted by g, is approximately 9.8 m/s^2.
Now we can calculate the work done:
Work = Potential Energy = mass x gravity x height.
Substituting the given values:
Work = 1.8 kg x 9.8 m/s^2 x 0.328 m.
Now we can calculate the final answer:
Work = 1.8 x 9.8 x 0.328 Joules.
Evaluating this expression will give you the amount of work required to stack the books one on top of another.
