Rolling ball background rectangle major grid lines axes x-axis and y-axis linear regression line data points as rectangles B data points as diamonds C data points as circles A data points as triangles D text layers Rolling ball time versus distance plots for four rolls Time (s) Distance (cm) y-axis labels 0 180 360 540 720 900 1080 1260 1440 1620 1800 x-axis labels 0 1 2 3 4 5 6 7 8 9 10

The first four questions are matching. Use the letters A, B, C, and D at the end of the lines on the xy scattergraph.

  1. _____ Ball not moving: stationary.
  2. _____ Ball slowing down.
  3. _____ Ball moving at a constant non-zero speed.
  4. _____ Ball speeding up.
  5. ___________________ Determine the speed of ball D.
  6. ___________________ Determine the speed of ball A.
  7. ___________________ Determine the speed of ball B between 4 and 5 seconds.
  8. ___________________ Determine the speed of ball C between 7 and 10 seconds.
  9. Madolehnihmw three hour run from Google Earth RipStik Alley background rectangle major grid lines axes x-axis and y-axis linear regression line Linear regression equation manually placed y = 1.61 x + -0.49 data points as rectangles text layers RipStik Alley Time (s) Distance (m) y-axis labels 0 4 8 12 16 20 24 28 32 36 40 x-axis labels 0 3 6 9 12 15 18 21 24 27 30
    ___________________ The graph above was generated by a RipStik rider. The x-axis is time in seconds, the y-axis is the distance in meters. The equation of the line is y = 1.61x − 0.49. What is the speed of the RipStik?
  10. ___________________ On Saturday 15 January I ran from Dolihner, Nett to Kinakapw, Madolehnihmw, covering 19.8 kilometers in three hours. I consumed four bottles of water, a mini-can of Pringles, and a bag of karindo. What was my velocity ѵ in kilometers per hour?
