High BASE jumps are those which are high enough for the jumper to reach terminal velocity. High BASE jumps are often called "slider up" jumps due to the use of a slider reefing device. High BASE jumps present different hazards than low BASE jumps. lamp 632

"WebWhen falling in the standard belly-to-Earth position, an average estimate of terminal velocity for skydivers is 120 mph (200 km/h), and a falling person will reach terminal velocity after about 12 seconds, falling some 450 m (1,500 ft) in that time.

WebTerminal velocity describes the equilibrium point in kinematics where atmospheric drag on a falling object becomes equal and opposite to the acceleration due to gravity. It depends on the object's weight, frontal area, drag coefficient and the density of the medium through which it is falling. In this example, a speed of 50% of terminal speed is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on. Higher speeds can be attained if the skydiver pulls in their limbs (see also freeflying). Meer weergeven Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example).
