The graph shows the time versus distance data gathered for four different balls in laboratory 022.
The first four questions are matching. Use the letters A, B, C, and D at the end of the lines on the xy scattergraph.
_____ Ball not moving: stationary.
_____ Ball slowing down.
_____ Ball moving at a constant non-zero speed.
_____ Ball speeding up.
___________________ Determine the speed of ball D.
___________________ Determine the speed of ball B.
___________________ Determine the speed of ball A between 0 and 2 seconds.
___________________ Determine the speed of ball C between 7 and 10 seconds.
A rolling ball cannot generate a vertical line on a time versus distance graph. Why?
__________ _________ The graph above was generated when I rode the RipStik on Monday. The x-axis is time in seconds, the y-axis is the distance in meters. The equation of the line is y = 200x + 20. What is the velocity of the RipStik (including units)?
_________ __________ If I kept on riding the RipStik at the above velocity for 180 seconds, use the given equation to determine how far I would go.
_________ __________ Palikir Elementary School is 100,000 centimeters away. If I rode to Palikir Elementary at the same velocity as I had on Monday, how long in seconds would that RipStik ride take?
_________ _________ Where not otherwise posted, what is the state speed limit on Pohnpei in miles per hour?
_________ _________ Toughie: Where not otherwise posted, what is the state speed limit on Pohnpei in kilometers per hour?
