 It's about one-two-hundredth as fast as a Peregrine Falcon In other words, 2 kilometers per hour is 0.0051 times the speed of a Peregrine Falcon, and the speed of a Peregrine Falcon is 195 times that amount. (a.k.a. Peregrine, a.k.a. Duck Hawk, Falco peregrinus)The Peregrine Falcon can reach speeds of up to 389 kph when diving. Falcons are sometimes sent to scare smaller birds away from airports to improve air traffic safety and were used in World War II to intercept carrier pigeons used by enemy forces. It's about one-six-hundredth as fast as The Speed of Sound In other words, 2 kilometers per hour is 0.0016 times the speed of The Speed of Sound, and the speed of The Speed of Sound is 617 times that amount. (in dry air at 20°C)The speed of sound in dry air at 20°C (68°F) is 343 m/s. Air is a relatively poor acoustic conductor, however, as sound will travel at speeds of between 5,390 kilometers per hour to 5,620 kilometers per hour in water, depending on its salinity. It's about one-seven-hundredth as fast as a Bullet (Handgun) In other words, 2 kilometers per hour is 0.0015 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 690 times that amount. (for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 1,380 kph. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990. It's about one-one-thousandth as fast as a Jet Fighter In other words, 2 kilometers per hour is 0.0008 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 1,200 times that amount. (for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)An F-16's maximum speed at altitude is approximately 2,400 kilometers per hour. The F-16 has a flight ceiling of approximately 15 km (9.32 mi). It's about one-one-thousand-five-hundredth as fast as a Bullet (Rifle) In other words, 2 kilometers per hour is 0.00061 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 1,650 times that amount. (5.56 x 45 mm, a.k.a. 5.56 NATO)A 5.56 x 45 mm cartridge is fired at a velocity of 3,294 kph. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces. It's about one-fifteen-thousandth as fast as The Space Shuttle In other words, 2 kilometers per hour is 0.000071744 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 13,938 times that amount. (Orbiter vehicle velocity)The space shuttle orbits at a speed of 27,877 kph. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process. It's about one-seventy-five-thousandth as fast as a Meteor In other words, 2 kilometers per hour is 0.000013 times the speed of a Meteor, and the speed of a Meteor is 77,000 times that amount. (formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")Small meteoroids enter the Earth's atmosphere at speeds between 40,000 kph and 260,000 kph, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 10,000 kph.
