  1. Use the video to calculate the speed of the red and blue car befroe it leaves the ledge? (Show your math.)
  2. How many seconds does the red car spend in the air?
  3. How many seconds does the blue car spend in the air?
  4. You and your friend are playing at the river. You both run horizontally off ledge and eventually land in the rive below. Who will land in the water first if you left the ledge at the same instant in time?
