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?

how long does it take the car to fall 56m?
what velocity does it take to go 129m/that time? 
1. 5.714 seconds
2. 50.5mph, 81.27kph, or 22.576mps 
1. 5.714 seconds
2. 50.5mph, 81.27kph, or 22.576mps (meters per second) 
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.
