It was a rather long problem, so I'm going to sum it up:
Some company made this racing game (Cars race around an 800 meter track and tries to avoid incidents such as other players equiped with penguin mines and flippy wet fish), but turns out, when the player competes against the computer, it's too easy.
At what rate must the cars accelerate so players are forced to use skill to maneuver around obstacles?
Acceleration is constant without any obstacles
The goal is to avoid players from making it around the track in under 20 seconds, assuming the player starts at rest.
What constant must be used for the cars' acceleration?
