$\text{slope}=\frac{({y}_{2}-{y}_{1})}{({x}_{2}-{x}_{1})}$

$\u0475=\frac{\Delta d}{\Delta t}$

distance `d` = velocity `ѵ` × time `t`

- The graph shows the time versus distance data gathered for four different ball speeds in laboratory 02.

`ѵ`of ball A. - __________ _____ Determine the velocity
`ѵ`of ball B. - __________ _____ Determine the velocity
`ѵ`of ball C. - __________ _____ Determine the velocity
`ѵ`of ball D.

- __________ _____ Determine the velocity
- __________ _____ Calculate the velocity
`ѵ`of a ball that rolls 2424 centimeters in six seconds. - __________ _____ Calculate the distance a ball with a velocity
`ѵ`of 777 cm/s will roll in six seconds. - __________ _____ Calculate the time for a ball with a velocity
`ѵ`of 243 cm/s to roll 729 centimeters. - For the following RipStik velocity data and chart:

- __________ _____ Determine the velocity
`ѵ`of the RipStik. - __________ _____ If the RipStik continued at that velocity for 60 seconds, how many centimeters would the RipStik travel?
- __________ _____ If the RipStik continued at that velocity for 1819 centimeters, how many seconds would the RipsStik travel?

- __________ _____ Determine the velocity
- The five graphs seen below plot time versus distance for a rolling ball. Time in seconds is on the x-axis. Distance in centimeters is on the y-axis.
