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
