Graphs for 500
Explain the acceleration for each segment of the
graph below.
Speed (m/s)
Accelerates from 0 to 10 in 2 seconds, or 6m/s/s.
Goes a constant speed (10 m/s) for 4 seconds.
Then decelerates from 10 m/s to 0 m/s. Then
stops completely for 2 seconds.

Final Jeopardy

• A ladybug is creeping down a sidewalk at 1 m/s.
  Sometime later, its speeding at 5 m/s. This
  could have happened if the lady bug accelerated
  at 1 m/s/s for 4 seconds. Is this the only way
  that the increase in speed could have happened?
  Explain.

possibilities 1 m/s/s for 4 s, 2 m/s/s for
2 s, 4 m/s/s for 1 s
