WebA typical skydiver on a belly-to-earth position will reach terminal velocity at a speed of approximately 120 mph (193 km/h) and will freefall for about 30-60 seconds before opening the parachute. Once a parachute is open it reduces the speed down to at least 90% and skydivers glide to the ground at a relatively low speed of 12 mph. WebJan 21, 2024 · From that height, you'd only be able to reach around 33km/h (20mph) at maximum, disregarding air resistance, well below the estimated 195km/h (122mph) terminal velocity of a skydiver. Basic physics dictates that kinetic energy, the real problem with falling, grows with the square of velocity.

Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object.
