If the parachute does not open, the trooper is trained to pull the reserve chute.

If I remember correctly an object falling, falls at 33 feet per second/per second. The speed doubles every second. But of course we have to factor in wind, resistance and all that. Final thing to remember is terminal velocity (fastest speed you can free fall) is some were around 220 MPH.
