Did you know?
WebIn skydiving, terminal velocity refers to the maximum speed that the skydiver can attain as he falls from the sky to the ground. A typical tandem skydiver in a belly-to-earth position will reach terminal velocity at approximately 120 mph (193 km/h) after 12 seconds of freefall and a fallen distance of 1,500 feet (450m). WebApr 18, 2015 · The parachute only works because it keeps your weight roughly the same (negligible increase), but increases your surface area by more than an order of magnitude. If it increased your weight by the same factor as your surface area, it would have no effect on your terminal velocity. – Shufflepants. Apr 18, 2024 at 21:51.
WebTerminal 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) … WebA skydiver jumps from a plane and wishes to achieve "terminal velocity." A possible model for the skydiver's velocity is given as.The combined mass of the skydiver and her various gear is 60 kilograms, and the acceleration due to gravity g, near the Earth, is 9.8 meters per second squared.
