- ___________________ On Wednesday evening 23 January 2008, I ran 6.55 kilometers in 40 minutes 18 seconds. What was my speed in meters per second?

Time (s) | avg A ball dist (m) | avg B ball dist (m) |
---|---|---|

0 | 0.00 | 0.00 |

1 | 4.71 | 3.31 |

2 | 7.97 | 5.70 |

3 | 10.79 | 7.78 |

4 | 12.92 | 9.61 |

5 | 15.07 | 11.22 |

6 | 17.91 | 13.50 |

slope (m/s): | 3.16 | 2.35 |

- ___________________ Does the above data confirm a hypothesis that time and distance are linearily related for a ball rolling on a level surface?
**Why**does the above data confirm or disconfirm a hypothesis that time and distance are linearily related for a ball rolling on a level surface?- ___________________ According the above data, which ball is faster, the A or the B ball?
- ___________________ What is the speed of the A ball in meters per second?
- ___________________ Using the above data, predict the distance the A ball would roll after 7 seconds.
- ___________________ Using the above data, predict the time it would take the A ball to roll 31.6 meters.
- ___________________ Will the ball obey your predictions above?
- Why, or why not, will the ball above obey your prediction? Use the back if you need more space.
