  2. Simplified Aid For EVA Rescue - Wikipedia

    en.wikipedia.org/wiki/Simplified_Aid_for_EVA_Rescue

    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.

  4. Foot per second - Wikipedia

    en.wikipedia.org/wiki/Foot_per_second

    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 .

  5. Specific impulse - Wikipedia

    en.wikipedia.org/wiki/Specific_impulse

    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 .

    The landing gear was deployed 10 seconds prior to touchdown, when the orbiter was at an altitude of 91 m (300 ft) and traveling 150 m/s (288 kn). A final flare maneuver reduced the orbiter vehicle's descent rate to 0.9 m/s (3 ft/s), with touchdown occurring at 100–150 m/s (195–295 kn), depending on the weight of the orbiter vehicle.

  7. Muzzle velocity - Wikipedia

    en.wikipedia.org/wiki/Muzzle_velocity

    For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...

  8. Foot per second squared - Wikipedia

    en.wikipedia.org/wiki/Foot_per_second_squared

    The foot per second squared (plural feet per second squared) is a unit of acceleration. [1] It expresses change in velocity expressed in units of feet per second (ft/s) divided by time in seconds (s) (or the distance in feet (ft) traveled or displaced, divided by the time in seconds (s) squared).

  9. Metre per second - Wikipedia

    en.wikipedia.org/wiki/Metre_per_second

    ft/s 3.2808 The metre per second is the unit of both speed (a scalar quantity ) and velocity (a vector quantity , which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second .
