how long does it take the car to fall 56m?
what velocity does it take to go 129m/that time?
A car drives straight off the edge of a cliff that is 56 m high. The police at the scene of the accident note that the point of impact is 129 m from the base of the cliff. How fast was the car traveling when it went over the cliff?

Wait disregard that - I am such an idiot right now. (I can't erase the former comments)
1. 3.379 seconds
2. 85.549mph, 137.678kmph, or 38.244mps (meters per second)
I was a little braindead before and miscalculated the projection formula by not doubling the gravitational free fall factor with each passing second.
NOTE: this does not count the concepts of mass vs wind resistance - just a simple projection calculation.
