by the time asafa reached 20m, the raptor will have blown through 60, and by the time asafa got to 40, the raptor would have finished. the raptor could give asafa powell a 50m headstart, then run him down and eat him for dinner. you? better hide.
and in case you dont know much about dinosaurs, the raptors in jurassic park were fictional in a number of ways, the most notable being size. a real velociraptor was about 3 ft high, actually the size of a turkey. deinonychus was about 5 ft high and utahraptor was significantly larger than a human. so for all intents and purposes, the raptors in jp were fake. however, a deinonychus or a utahraptor could likely have had the 'real' performance stats of the jp raptors.
