The graph on the right shows the time versus distance data gathered for three different RipStik runs A, B, and C. The first three questions are matching. Use the letters at the end of the lines on the xy scattergraph.

  1. _____ RipStik moving at a constant speed, no acceleration.
  2. _____ RipStik moving faster at a constant rate of acceleration.
  3. _____ RipStik moving with a non-constant acceleration .
  4. _______ ___________ Determine the speed of RipStik run C.
  5. _______ ___________ Determine the speed of RipStik run B from 0 to 3.5 seconds.
  6. _______ ___________ Determine the speed of RipStik run B from 4.5 to 5 seconds.
  7. RipStik Acceleration Data
    time (s) dist (cm) velocity(cm/s)
    0 0 0
    2.50 200
    3.75 400
    _______ ___________ Using the data in the table, calculate the speed of the RipStik between the 0 cm and 200 cm.
  8. _______ ___________ Using the data in the table, calculate the speed of the RipStik between the 200 cm and 400 cm.
  9. _______ ___________ A RipStik is accelerated from 100 cm/s to 225 cm/s in 2 seconds. Calculate the acceleration of the RipStik.
  10. __________ ______ Using the equation d = ½gt², calculate the distance a ball will fall in three seconds. Use 980 cm/s² for the acceleration of gravity g.
  11. __________ ______ Given d = ½gt², where g = 980 cm/s², what is the duration in seconds for a marble to fall from a height of 7840 cm?
  12. Does a dropped ball fall faster and faster? How do you know this?
  13. ____________________ A marble with a mass of 5.2 grams rolls 30 centimeters in 0.60 seconds. Calculate the momentum of the marble.
  14. ____________________ 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.
  15. ____________________ Calculate the kinetic energy for a 30 kilogram child traveling at a velocity of 0.7 m/s on a RipStik.
  16. Write Newton's first law:


  17. _____________ A RipStik was accelerated from 0 m/s to 1.8 m/s in three seconds by a 52 year old instructor with a mass of 63 kilograms. Calculate the force that generated the acceleration.
  18. As seen in the image, three identical vials have equal amounts of a green liquid. Based on what you learned from the soap, how would you explain that two are floating while one has sunk to the bottom?

  19. _______ A team of Hooke's law researchers measured the extension in centimeters versus the force in gram-force for an elastic band. Their data is plotted on the graph. Is the elastic a linear elastic material?
  20. Support your answer above with an explanation. What is the evidence that the material either is or is not a linear elastic material?
