The data in the circle on the page above provides speed into a group of marbles for a single inbound marble and the speed of the single marble kicked out of that group of marbles. Plot the data on the graph below. Using a ruler, plot a line that best runs through the data points.
__________ _________ What is the slope of the line plotted through the data?
____________________ Is the speed out equal to, less than, or greater than the speed in?
_____________ Toughie: if the speed out is not equal to the speed in, by what percentage has the speed changed?
_____
Identify by the letter which of the mathematical relationships on the graph represents the time versus distance relationship for a RipStik moving at a constant linear velocity with no acceleration.
_____
Identify by the letter which of the mathematical relationships on the graph represents the time versus distance relationship for a RipStik moving at an increasing velocity at a constant acceleration.
_____
Identify by the letter which of the mathematical relationships on the graph represents the height versus velocity relationship for a marble rolling from a height h down a banana leaf and onto a flat table.
