How fast do objects fall in mph? - Answers
Web1 okt. 2024 · The shape of the object. For a human, the drag coefficient C d is about 1 in a belly down, horizontal orientation and 0.7 in head down position. Typically in this position, terminal velocity is about 120 mph or 54 m/s. Instantaneous and terminal velocity for … WebThe density is now 1/8 x 1/2 x 1/2 x 1/2, or 1/64. We can get the same heating by multiplying: Mach 2.2 x 2 x 2 x 2 = Mach 17.6 (the real Mach number varies with density). Mach 1 is close to 1000km/hour. So we are now going at about 17,600 km/hr (11,000 mph) at 144 km elevation and that is hot enough to melt aluminum. man to woman transformation body swap
