  2. Geely Galaxy Starship 7 - Wikipedia

    en.wikipedia.org/wiki/Geely_Galaxy_Starship_7

    The Starship 7 is capable of accelerating from 0–100 km/h (0–62 mph) in 7.5 seconds. The vehicle offers two Aegis Short Blade lithium iron phosphate (LFP) battery options: an 8.5 kWh battery with an all-electric range of 55 km (34 mi) on the CLTC cycle and a larger 19.09 kWh battery providing up to 120 km (75 mi) of electric range.

  3. Speed of sound - Wikipedia

    en.wikipedia.org/wiki/Speed_of_sound

    T 25 is 298.15 K (= 25 °C = 77 °F), giving a value of 346.1 m/s (= 1 135.6 ft/s = 1246 km/h = 774.3 mph = 672.8 kn). In fact, assuming an ideal gas , the speed of sound c depends on temperature and composition only, not on the pressure or density (since these change in lockstep for a given temperature and cancel out).

    4–7 mph 6–11 km/h 1.6–3.3 m/s 1–2 ft 0.3–0.6 m Small wavelets still short but more pronounced; crests have a glassy appearance but do not break Wind felt on face; leaves rustle; wind vane moved by wind 3 Gentle breeze 7–10 knots 8–12 mph 12–19 km/h 3.4–5.4 m/s 2–4 ft 0.6–1.2 m

  5. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    (mph) (km/h) (m/s) Subsonic <0.8 <530 <609 <980 <273 Most often propeller-driven and commercial turbofan aircraft with high aspect-ratio (slender) wings, and rounded features like the nose and leading edges. The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1.

  6. 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 .

  7. Parker Solar Probe - Wikipedia

    The second flyby of Venus on December 26, 2019. The velocity decreases by 2.9 km/s to 26 km/s (red circle), shifting the spacecraft to a new orbit closer to the Sun. Within each orbit of the Parker Solar Probe around the Sun, the portion within 0.25 AU is the Science Phase, in which the probe is actively and autonomously making observations.

  8. Arcimoto FUV - Wikipedia

    en.wikipedia.org/wiki/Arcimoto_FUV

    The FUV's 77 hp (57 kW) electric motor allows a top speed of 75 mph (121 km/h) and acceleration to 60 mph (97 km/h) in 7.5 seconds. [2] [7] Arcimoto measures its range in a city environment at 102 miles (164 km). The lithium-ion battery with a capacity of 20 kWh also allows the driver to drive at 55 mph (89 km/h) for 66 miles (106 km) and at 70 ...
