Describe book lungs.

A book was lengthened by 8 pages for the second edition. If the book was originally 200 pages long, what was the percent increase?

When you push a 1.92-kg book resting on a tabletop, you have to exert a force of 2.05 N to start the book sliding. Once it is sliding, however, you can use a force of only 1.03 N to keep the book moving with constant speed. What are the coefficients of static and kinetic friction between the book and the tabletop?

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?

A force of gravity pulls downward on a book on a table. What force prevents the book from accelerating downward?

You borrow a book from the library to read during your vacation. On the first day of vacation, you read one quarter of the book. On the second day, you read half of the remaining pages. On the third day, you finish the last 120 pages of the book. How many pages does the book have?

A0.60-kg book slides on a horizontal table. The kinetic friction force on the book has magnitude 1.2 N.

How much work is done on the book by friction during a displacement of 3.0 m to the left?

Rahul sits in a chair reading a book. Which force is equal to the force Rahul exerts on Earth?

A. Rahul’s weight
B. the chair’s weight
C. the sum of the weights of Rahul and the book
D. the sum of the weights of the chair, Rahul, and the book.

A book publisher has fixed costs of $\$300,000$ and variable costs per book of $\$8$. The book sells for $\$23$ per copy. If the fixed cost increased, would the new break-even point be higher or lower?

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.
