Assuming he weighed 100 kg, how much force would he have experienced when he hit the ground? Let's say 7 stories is 70 feet, or 21.336 meters. I know that F = ma, but that just results in 980 N of force. I understand that there are numerous other factors, so let's say he hit his head and that the top had an area of 0.5 ft^2 (0.04645 m^2). Also assume that the impact was near instantaneous, so perhaps the duration of impact was 1 microsecond. I know that there's the issue of linear and rotational motion, but I want to ignore that.

I don't know what other factors would have influenced the "force." Kinetic energy? Momentum? I know it's a weird question, but I've been thinking for it all day and don't know how to approach it.
