The top speed of the world's fastest roller coaster, Formula Rossa. 90: 320: 200: 3 × 10 −7: Typical speed of a modern high-speed train (e.g. latest generation of production TGV); a diving peregrine falcon—fastest bird; 320 km/h or 200 mph is a parameter sometimes used in defining a supercar. [15] 91: 328: 204: 3.04 × 10 −7
≈ 340 m/s in air at sea level ≈ 295 m/s in air at jet altitudes metre per second (SI unit) m/s ≡ 1 m/s = 1 m/s mile per hour: mph ≡ 1 mi/h = 0.447 04 m/s: mile per minute: mpm ≡ 1 mi/min = 26.8224 m/s: mile per second: mps ≡ 1 mi/s = 1 609.344 m/s: speed of light in vacuum: c: ≡ 299 792 458 m/s = 299 792 458 m/s: speed of sound in ...
(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.

921–3,836 mph (1,482–6,173 km/h; 412–1,715 m/s) The supersonic speed range is that range of speeds within which all of the airflow over an aircraft is supersonic (more than Mach 1). But airflow meeting the leading edges is initially decelerated, so the free stream speed must be slightly greater than Mach 1 to ensure that all of the flow ...
Reducing the weight of the bike + rider by 1 kg would increase speed by 0.01 m/s at 9 m/s on the flat (5 seconds in a 32 km/h (20 mph), 40-kilometre (25 mile) time trial). The same reduction on a 7% grade would be worth 0.04 m/s (90 kg bike + rider) to 0.07 m/s (65 kg bike + rider).
The biggest concern driving markets is that inflation doesn't continue its downward trend toward the Federal Reserve's 2% target. Two key readings will greet investors in the week ahead on that front.
In the Heinlein work the fast lane runs at 100 mph (160 km/h), and the first "mechanical road" was built in 1960 between Cincinnati and Cleveland. The relative speed of two adjacent belts is 8.0 km/h (5 mph) [28] (in the book, the fast lane stops while the second lane keeps running at 153 km/h (95 mph)). In the Wells and Asimov works there are ...
