You are reshelving books in a library. You lift a book from the floor to the top shelf. The kinetic energy of the book on the floor was zero and the kinetic energy of the book on the top shelf is zero, so no change occurs in the kinetic energy even though you did some work in lifting the books. Is the work-kinetic energy theorem violated?

Explanation

To determine whether the work-kinetic energy theorem is violated when lifting a book from the floor to the top shelf, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Initial and Final States**:
- When the book is on the floor, its kinetic energy (KE_initial) is zero because it is at rest (velocity = 0).
- When the book is placed on the top shelf, its kinetic energy (KE_final) is also zero because it is again at rest.
