Drogue parachute deployed at 22,000 ft (6,700 m) slowing descent to 365 ft/s (111 m/s) and stabilizing capsule. T+00:09:45 Snorkel Deploy Fresh air snorkel deploys at 20,000 ft (6,100 m). (ECS) switches to emergency oxygen rate to cool cabin. T+00:10:15 Main Parachute Deploy Main parachute deploys at 10,000 ft (3,000 m).
is the standard gravity (in m/s 2 or ft/s 2). In rockets, due to atmospheric effects, the specific impulse varies with altitude, reaching a maximum in a vacuum. This is because the exhaust velocity isn't simply a function of the chamber pressure, but is a function of the difference between the interior and exterior of the combustion chamber .
d MT = braking distance, m (ft) V = design speed, km/h (mph) a = deceleration rate, m/s 2 (ft/s 2) Actual braking distances are affected by the vehicle type and condition, the incline of the road, the available traction, and numerous other factors. A deceleration rate of 3.4 m/s 2 (11.2 ft/s 2) is used to determine stopping sight distance. [6]
SAFER has a mass of approximately 83 lb (38 kg) and can provide a total change in velocity of at least 10 ft/s (3 m/s). [5] It was also tested during flight STS-92 when astronauts Peter Wisoff and Michael López-Alegría performed test maneuvers, flying up to 50 feet (15 m) while remaining tethered to the spacecraft.
It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second . Abbreviations include ft/s , fps , and the scientific notation ft s −1 .
In time, this resulted in major land subsidence by the 1970s with local areas having 0.30 to 8.5 m (1 to 28 ft) of subsidence. With the creation and use of the California Aqueduct along these regions, surface water being transported put a halt on significant compaction and a recovery in ground water levels now with less ground water pumping. [22]
It is a constant defined by standard as 9.806 65 m/s 2 (about 32.174 05 ft/s 2). This value was established by the third General Conference on Weights and Measures (1901, CR 70) and used to define the standard weight of an object as the product of its mass and this nominal acceleration .
