Using all of the students in your class, find the actual time it takes to pass the book. Actual time to pass the book: _____

Drop a book and a sheet of paper, and you'll see that the book has a greater acceleration-g. Repeat, but place the paper beneath the book so that it is forced against the book as both fall, so both fall equally at $g$. How do the accelerations compare if you place the paper on top of the raised book and then drop both? You may be surprised, so try it and see. Explain your observation.

A string is tied to a book and pulled lightly as shown at right. The book remains in contact with the table and does not move.

a. Draw a free-body diagram for the book. Label each of the forces exerted on the book as you were instructed in the tutorial Forces. String

b. How do the forces exerted on the book in this case compare to the forces exerted on the book when the string is not present? List any forces that are the same (i.e., same type of force, same direction, and same magnitude) in both cases. Make a separate list of forces that change (or are not present) when the string is pulled.

If a book is located on a table, how many forces should be shown in a free-body diagram of the book? Describe them.

What inference rule is illustrated by the argument given? If Martina is the author, then the book is fiction. But the book is nonfiction. Therefore Martina is not the author.

Mike has read

$$\frac { 1 } { 3 }$$

of his book. What fraction of his book does he still have to read? What percent of his book does he still have to read?

Using a chart like the one below, list the characteristics of good radio journalism, as well as the characteristics of a well-written book review and book-jacket blurb.

An eraser with a mass of 100 g sits on a book at rest. The eraser is initially 10.0 cm from any edge of the book. The book is suddenly yanked very hard and slides out from under the eraser. In doing so, it partially drags the eraser with it, although not enough to stay on the book. The coefficient of kinetic friction between the book and the eraser is 0.150. (a) The sign of the work done by the force of kinetic friction of the book on the eraser is (1) positive, (2) negative, or (3) zero work is done by kinetic friction. Explain. (b) How much work is done by the book's frictional force on the eraser by the time it falls off the edge of the book?

Kendra bought 4 copies of the same book for the members of her book club at an online bookstore. She got free shipping because her total was at least $50. What was the minimum price of each book? Give and solve an inequality.

It is hard to imagine that there can be enough air between a book and a table so that there is a net upward (buoyant) force on the book despite the large downward force on the top of the book. About how many air molecules are there between a textbook and a table, if there is an average distance of about 0.01 mm between the uneven surfaces of the book and table?

For the books in the given figure, there is a force $F$ from the table supporting the book on the bottom. Identify two action-reaction force pairs for each of the following objects: (a) the table, (b) the book on top, (c) the book on the bottom, and (d) the Earth.

You have decided to write a novel. You learn that it is now easy to publish a book on your own, but you want to protect your copyright. You plan to sell both a print edition of the book and also an electronic book (e-book) that you will sell from your Web site. Research copyright law and Find out what you must do as an author to copyright your book and protect it in both print form and on the Internet.

Why is the following situation impossible? A book sits on an inclined plane on the surface of the Earth. The angle of the plane with the horizontal is $60.0^{\circ}$. The coefficient of kinetic friction between the book and the plane is 0.300. At time t = 0, the book is released from rest. The book then slides through a distance of 1.00 m, measured along the plane, in a time interval of 0.483 s.

A container has a square base. The area is $800 \mathrm{~cm}^2$. The size of a book is 25 cm by 30 cm. Can the book lie flat on the base of the container?

Compare the side length with the dimensions of the book.
