3.) Place a book on a table and stand a small bottle on top of it. Pull the book toward you with a quick jerk. Note the action of the bottle. Stand the bottle on the book again and pull the book across the table with a steady pull. How does the bottle move? Now pull the book and stop it suddenly. Explain the action of the bottle in all three instances.

Explanation / Answer
The coefficient of restitution (COR) of two colliding objects is a fractional value representing the ratio of speeds after and before an impact, taken along the line of the impact. Pairs of objects with COR = 1 collide elastically, while objects with COR < 1 collide inelastically. For a COR = 0, the objects effectively "stop" at the collision, not bouncing at all.
