Using the formula
determine the velocity v for a marble rolling on a table launched from a height h of 49 cm on a banana leaf.

____________________ In laboratory four a blue marble went a distance of 30 centimeters in 0.6 seconds. What is the velocity v for the marble?
____________________ In laboratory four a 2.0 gram blue marble went a distance of 30 centimeters in 0.6 seconds. What is the momentum p for the marble?
On Thursday I demonstrated that "marbles in equals marbles out" and that "speed in equals speed out." How do the marbles know what to do? What do you think? In a paragraph or two, share with me your thoughts and reflections on how the marbles know what to do. Do not simply throw around vocabulary - be careful to write plainly and clearly. Explain the terms you choose to use. Cite examples from your own playing with the marbles (you did play with the marbles, didn't you?). I will be looking for thoughtfull, well-reasoned, and sensible analysis.
