Yes; while on the shelf it has potential energy due to gravity of mgh where m = mass and g =gravity acceleration and h is height fom floor.
As it falls its potential energy is converted to kinetic energy mv squared/2 where v = velocity

Well, honey, that book on the high shelf has more potential energy because it's got farther to fall. Gravity's just itching for the chance to show off its power and send that book plummeting down to the ground. So, the higher the book, the more potential energy it's got stored up just waiting to be unleashed.
I presume you mean 25 mm (25 millimeters) wide, not 25 mega-meters (25,000 km, which is about twice the diameter of the Earth), and that this is not a trick question about a shelf 1 m wide meaning deep, so the answer depends on what the length of the shelf is. A meter (I'll use my nation's spelling, you use yours!) is 1,000 mm, so we divide 1,000 by 25. The answer is 40.
There are 5! (that is, 120) distinct ways to arrange five items. Only 1 of them will have the books in alphabetical order by title. So the probability that it happens by random is 1/120.
1200 pages. This is a simple question. All you have to do to arrive at your answer is multiply 200 times 6. ___ The above answer could be wrong, if the books are on a typical shelf. Page 1 of book 1 is on the right side, page 200 of the last book is on the left side. So, the bookwork doesn't have to go through the pages of the first volume, and of the last volume. ___ The above answers also assume that the bookworms are eating the entire pages rather than just a little bit of each as it burrows a hole. So, to answer we would not only need to know how the books are arranged, but also how the worm eats.
The math book was as heavy as a mountain.
