Question

A book is at rest on a flat table. The book is pushed across the table, causing it to move and eventually come to rest again. How does the potential and kinetic energy change during this process?

o The potential and kinetic energy will stay the same unless the book speeds up or slows down.
o The potential and kinetic energy decreases as the book comes to rest again.
o The potential energy increases as the book is pushed across the table. The kinetic energy stays the same.
o The potential energy will stay the same if the book stays on the table. The kinetic energy increases as the book is pushed across the table.

Answer 1

D

Step-by-step explanation:

At rest there is no Kinetic energy

As the book is pushed, kinetic energy will increase and then remain the same unless the book speed changes...potential energy will remain the same . Kinetic energy will decrease as the book comes to a rest and again, the potential energy will remain.
