  1. The graph shows the time versus distance data gathered for four different ball speeds in laboratory 02.
    Rolling balls background rectangle major grid lines axes x-axis and y-axis linear regression line linear regression line linear regression line linear regression line data points as circles data points as rectangles data points as diamonds data points as triangles text layers Rolling balls Time (s) Distance (cm) y-axis labels 0 50 100 150 200 250 300 350 400 450 500 x-axis labels 0.0 1.0 2.0 3.0 4.0 5.0 A B C D
    1. __________ _____ Calculate the velocity ѵ of ball A.
    2. __________ _____ Calculate the velocity ѵ of ball B.
    3. __________ _____ Calculate the velocity ѵ of ball C.
    4. __________ _____ Calculate the velocity ѵ of ball D.
  2. For the following RipStik velocity data and chart
    RipStik velocity, time versus distance
    1. __________ _____ Calculate the velocity ѵ of the RipStik.
    2. __________ _____ If the RipStik continued at that velocity for 60 seconds, how far would the RipStik go?
    3. __________ _____ If the RipStik continued at that velocity for 10,000 centimeters, how long in seconds would it take the RipStik?
  3. A rolling ball cannot generate a vertical line on a time versus distance graph. Why?

[The following includes formulas written in MathML. FireFox or Safari browsers must be used to render the formulas correctly.]

slope m= ( y2 − y1 ) ( x2 − x1 )
y = mx + b
Where m is the slope and b is the y-intercept
distance d = velocity ѵ × time t
d = ѵt
If there is a y-intercept: d = ѵt + b
where b is in the units of distance
ѵ= Δd Δt
