I'm writing a fic, and I need some advice. Character T is a young man who's investigating the death of a female reporter who was investigating the organisation he is involved with. At some point he gets in a car with Character A, the man who killed the reporter, but he doesn't know this at the time. Whilst talking, Character A reveals that he did, in fact, kill the reporter and Character T, fearing for his life, opens the car door and jumps out.
Let's say the car was moving at about 35-40 miles per hour (55-65 kph), and Character T is a healthy and physically fit 16 year old. He jumps out and lands on his front. How bad would the injuries be, could he get up and walk or run? I doubt it myself, but I tried searching the internet and found nothing helpful.
EDIT: Sorry, I'll be more specific. He lands on his hands and knees. I'm pretty sure that would break something, but as to the severity I don't know.
