How did speed of marble that comes off end of line change


Assignment

PRE-LAB QUESTIONS

1) A billiard ball collides head-on with billiard ball at rest.

a) Sketch a position vs. time graph for each ball, include position before the collision, once the collision occurs and after the collision.

b) What can be said about the conservation of momentum for the collision? Explain your answer.

2) Write down the total momentum for two marbles of mass, m, both moving at velocity, v . What is the kinetic energy of the system?

3) When you drop two marbles at once, why doesn't only one marble come off the end twice as fast? Write down the kinetic energy of one marble with mass m and velocity 2v and compare this to your answer in Experiment 1 Post Lab Question 4 to check.
Note: Assume the collisions are perfectly elastic.

Post-Lab Questions

1) What kind of collision is exhibited by the marbles in this experiment and why?

2) When one marble hit the end of the line of marbles, how many shot off the other end? Describe the momentum of the set of marbles before and after the collision (assume elastic collisions).

3) How did the speed of the marble that comes off the end of the line change as you increased the speed of the marble that travels down the chute? Use what you know about the conservation of momentum to describe what is happening.

4) What happened when you sent two marbles down the runway? Is this what you predicted? Explain why or why not.

5) How did the result change when both marbles were moving toward each other before the collision?

6) What do you predict would happen to two marbles after a collision if you slowly rolled a marble down the runway and then flicked a second marble faster in the same direction?

Format your assignment according to the following formatting requirements:

(1) The answer should be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.

(2) The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.

(3) Also include a reference page. The Citations and references should follow APA format. The reference page is not included in the required page length.
