The graph shows the time versus distance data gathered for four different ball/marble rolls laboratory 02. 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. 
   ___________________ 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?
11. _________________ Calculate your speed if you walk 36.8 meters in 18.4 seconds
12. _________________ At the walking speed calculated above, how long in seconds for you to walk the 1000 meters from the A101 classroom to Palikir Elementary School?
