Summary
Skydivers reach approximately 200 km/h terminal velocity in free fall.
Terminal velocity is the speed when gravity equals air resistance. In belly-down position, this is about 200 km/h. In head-down diving position, 300 km/h is possible. Felix Baumgartner jumped from space in 2012 and exceeded the speed of sound at 1,357 km/h! The human body can accelerate much faster in the atmosphere than you might think.
