For each of the pictures below, draw the free-body diagram on the book. Be careful to include all forces on the book.

For 3, 4, and 5 assume that the book has a constant velocity

For 3 , push the book to get it moving. Is it more difficult to get the book started or to keep it moving?

Redo the free-body diagrams for 3, 4, 5 under the assumption that the book's velocity is changing.

For #6, draw the free body diagram for the upper and the lower book and for the books as a single unit.
