  1. ____________________ Identify by the data point shapes (circles, squares, or diamonds) 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.
  2. ____________________ Identify by the data point shapes (circles, squares, or diamonds) 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.
  3. ____________________ Identify by the data point shapes (circles, squares, or diamonds) 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.
  4. Marbles on ruler track ___________ If two marbles are rolled into a line of five marbles, how many marbles will roll out from the end of the line?
  5. ____________________ Two marbles roll 45 centimeters in 0.60 seconds. Calculate the speed of the marbles.
  6. ____________________ If each marble in the above problem is 5.0 grams, calculate the total momentum for both marbles using the speed calculated in the problem above.
  7. ____________________ Calculate the gravitational potential energy relative to the floor for a 30 kilogram child standing on a table one meter high. Use 9.8 m/s² for the acceleration of gravity g.
  8. ____________________ Calculate the kinetic energy for a 30 kilogram child traveling at a velocity of 1.5 m/s on a RipStik.
  9. ____________________ A marble is rolled from a height of 20 cm on a banana leaf marble ramp. Calculate the velocity of the marble using the theoretic equation ѵ=44.2h to calculate the velocity of the marble at the bottom of the ramp.
  10. Marbles on ruler track ______ Suppose a single 5.0 gram marble hits a line of five marbles that each have a mass of 2.5 grams. How many marbles do you think might be "kicked out" from the end of the line of small marbles?
  11. Using the back, explain your answer to number nine above. Why do you think that number will be kicked out?
