Question

A book is at rest on a flat table. A person gives the book a shovel, and it slide down across the table. The book eventually comes to rest again near the edge of the table. How does the potential and kinetic energy change during this process a the potential stays the same since the book is on the table the kinetic energy stays the same since the book was only shoved be the potential energy will stay the same as long as the book stays in the table the kinetic energy will increase from the book is shoved, and then gradually decrease as it slides along the table, and then comes to a rest on the edge see the potential energy increases as the book is pushed across the table. The kinetic energy stays the same since the book with shoved or D the potential and kinetic energy are the same while the book is sitting on the table. They both increase when the book is shoved, and decrease as the book comes to arrest.

Answer 1

The correct answer is:

The kinetic energy increases when the book is shoved, and then gradually decreases as it slides along the table and comes to a rest near the edge. The potential energy remains the same throughout this process.
