slope= ( y2 − y1 ) ( x2 − x1 )
ѵ= Δd Δt
distance d = velocity ѵ × time t

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

  5. For the following RipStik velocity chart:
    RipStik velocity, time versus distance
    1. __________ _____ Determine the velocity ѵ of the RipStik.
    2. __________ _____ If the RipStik continued at that velocity for 20 seconds, how many centimeters would the RipStik travel?
    3. __________ _____ If the RipStik continued at that velocity for 8600 centimeters, how many seconds would the RipStik travel?
  6. 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.
