Does this stunt go against the laws of physics?

Ghost Rider version

This video from the movie "Ghost rider" goes against the laws of physics. Gravity would have pulled the bike down but instead, it continues to go up.

Height of man sitting on motor cycle ~ 58 inches

Distance of motorcycle from the truck~ 116 inches

Height of trucks: 12 feet

Width of trucks: 68 inches

Initial Velocity: 0.0

Final Velocity: 10t = 10 (19.9) = 199 m/s

Distance: 68 (width of truck) * 17 (# of trucks) / 19.9 (time in seconds) = 58.09

Height from the motorcycle to the ground: 128 feet.

Acceleration = 7 meters per seconds

He accelerated 7 meters in a one second.

Real life version (Evil Knievel)

This video is almost like the one from the movie exept it is a real life stunt performed by a a stuntman named Evil Knievel. The only difference between this stunt and the one from the movie is that in this stunt instead of jumping over 17 trucks, Evil Knievel jumped over 17 vans.
