1. ____________________ What is a taw?

2. ____________________ What is a duck?

3. ____________________ If one marbles collides with a line of five marbles on a ruler track, how many marbles are ejected and roll on off the track?

4. ____________________ If three marbles collide with a line of five marbles on a ruler track, how many marbles are ejected and roll on off the track?

5. Why do you think the marbles know what to do?

6. Explain how the speed of the marbles colliding with a line of marbles on a marble track affects the speed of the marbles ejected from the line.

7. ____________________ A 20.2 g taw covered 30.0 cm in 0.59 seconds. What is the speed of the taw?

8. ____________________ A 20.2 g taw covered 30.0 cm in 0.59 seconds. What is the linear momentum of the taw?
