Definition: The unit kilometers per hour (symbol: km/h) is a unit of speed expressing the number of kilometers traveled in one hour. History/origin: The unit of kilometers per hour is based on the meter, which was formally defined in 1799. According to the Oxford English Dictionary, the term kilometer first came into use in 1810. It was not until later in the mid-late 19 th. In the air, the answer is no and yes. A modern aircraft such as the Airbus A380 flies at a cruising speed of about 900 km/h. Its actual speed over the ground can vary quite a lot depending on.

Note that the speed of sound varies according to the medium it travels through, but since things traveling on Earth are surrounded by air at all times, we will consider the speed of sound in air, which happens to be 767 mph (or 1234 km/h) The US military aims to fly a hypersonic plane at 20 times the speed of sound by 2016. The X-plane will travel at Mach 20 (roughly 20,900 km/h), which means it could fly to any place on earth in. In principle, he has a constant speed of 50 km/h, but he can drive at a lowers peed and accelerate earlier, provided that the speed on the line A-A is exactly 50 km/h. When the front of the vehicle passes the line A-A, the throttle control shall be shifted to the maximum throttle position as rapidly as possible and kept in this position until the rear of the vehicle passes the B-B As luck would have it, your weapon fires at the exact same speed that you are traveling. So, you are flying along at 300 km/h and you are about to shoot a bullet/cannon/whatever in the opposite.

Mach is the ratio of an object's speed to the speed of sound. For example, something traveling at Mach 5 is traveling at 5 times the speed of sound. The speed of sound varies depending on many factors. In dry air, at 0 degrees Celsius, the speed of sound is about 331.3 meters per second The speed of sound through warm air at sea level has been measured at 346 meters per second or 0.346 km per second. That is the same as a car traveling about 780 miles per hour! Even most jet airplanes do not travel that fast. When a plane does go faster than speed of sound, it is said to break the sound barrier and a soni The speed of sound IS 343 m/s; if, you are at sea level ( 1 atmosphere pressure) and the temperature is 20 C ( or 68 F) and the air is dry. However if; the temperature is 27C (or 80F )' then the speed of sound is 347.5 m/s In km/h, this is: 330 ÷ 1000 = 0.33 km/s. 0.33 × 3,600 = 1,188 km/h. Making calculations Different calculations can often be needed to work out rates such as speed, and sometimes units may need.

** In 1906 Dorothy Levitt broke the women's world speed record for the flying kilometer, recording a speed of 91 mph (146**.25 km/h) and receiving the sobriquet the Fastest Girl on Earth. She drove a six-cylinder Napier motorcar, a 100 hp (74.6 kW) development of the K5, in a speed trial in Blackpool.. While record keeping has not been as extensive, a report in 1974 confirmed that a subsequent. Distance covered 240 km by car with speed 60 km/h Distance covered 80 km by train with speed 100 km/h and rest distance covered 200 km by bus with speed 50 km/h Total distance covered = (240 + 80 + 200) km = 520 km. Question 10. The speed of sound in air is about 330 ms-1. Express this speed in kmh-1. How long will the sound take to travel 99 km

- e the speed of sound
- So, it is reasonable that the speed of sound in air and other gases should depend on the square root of temperature. While not negligible, this is not a strong dependence. At 0ºC , the speed of sound is 331 m/s, whereas at 20.0ºC it is 343 m/s, less than a 4% increase. Figure 3 shows a use of the speed of sound by a bat to sense distances
- The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light

-Max speed (around 35 km/h): Motor section, minForwardGearRatio=19.5. increasing this value will lower max speed-Max speed backwards (around 7-8 km/h) Motor section, minBackwardGearRatio=50 same as abowe-Acceleration (needs to be lowered for a more heavy feeling to it The speed here is 20 km/h. Vehicles have meters in them to measure speed and distance both. The meter that measures speed is called the speedometer while the meter that measures distance is called the odometer. Both these meters are present near the ignition point of every vehicle where the pressure dependencies are given by P 1, P 2 and P 3, and the relaxation frequencies are f 1 and f 2.. Whilst the physics underlying the absorption of **sound** by seawater has become more securely based with time, there remains scope for further improvements in the data quality and in the best method of presentation The speed of sound varies depending on the type of medium through which it moves, explains Livescience. When traveling through Earth's atmosphere at sea level, and with a constant air temperature of 59 degrees Fahrenheit, sound travels at just over 761 miles per hour

An average speed across both runs of 763.035 mph (1,226.986 km/h) - and an emphatic new world land-speed record! The two huge booms that rang out over the site during Andy's outward and return run sent his crew into spontaneous cheers - though because he was actually inside the vehicle that caused those sonic booms, he couldn't hear them himself Russia recently deployed first 'Avangard' Hypersonic missile in its defence system. This hypersonic missile can fly 20 times faster than the speed of sound (33,000 km/h). According to Vladimir Putin, it can't be caught by any radar or defence system due to its technology and speed The speed of sound is normally calculated using the values of a standard atmospheric day. A standard atmospheric day refers to a sea level pressure of 29.92 in-Hg (1013.2 mb) and a temperature. 800-Hz sound from its siren? The speed of sound on this day is 345 m/s.

Kilometre per hour (American spelling: kilometer per hour) is a unit of both speed (scalar) and velocity (vector).The symbol is km/h or km·h −1.It is often spoken and sometimes written as klicks or kays in slang usage That's a ways off from pummeling past the speed of sound, or 761 mph (1,225 km/h), but it's one of many feats the car, called Bloodhound, will attempt over the next 12 to 18 months.In 2020 or. tude of 180.0 km. If the projectile's initial speed was 3.00 km/s, how long did it take the projectile to reach its maximum height? 3. The fastest speeds traveled on land have been achieved by rocket-powered cars. The current speed record for one of these vehicles is about 1090 km/h, which is only 160 km/h less than the speed of sound in air Top-Speed (km/h) 1 Alphonso Davies. 35.94.

14 A car travels 100 km. The journey takes two hours. The highest speed of the car is 80 km / h, and the lowest speed is 40 km / h. What is the average speed for the journey? A 40 km / h B 50 km / h C 60 km / h D 120 km / h 13 What does the area under a speed-time graph represent? A acceleration B average speed C deceleratio Speed and accident risk. A higher speed increases the likelihood of an accident. Very strong relationships have been established between speed and accident risk: The general relationship holds for all speeds and all roads, but the rate of increase in accident risk varies with initial speed level and road type During the X-15 program, 13 of the flights (by eight pilots) met the USAF spaceflight criteria by exceeding the altitude of 50 miles (80.47 km. 264,000ft.), thus qualifying the pilots for astronaut status; some pilots also qualified for NASA astronaut wings. Its fastest speed recorded is 4,519 mph (7,273 km/h) while manned by pilot Pete Knight Please enter distance or time, the other value will be calculated. One year is counted as 31557600 seconds (365 1/4 days). Examples: the average distance of the moon from earth is 384400 kilometers The speed of light is faster than the speed of sound. In addition, lightning creates thunder, therefore it happens first, therefore must be faster. See the related link for more information

It achieved a speed of 387 km/h (240 mph), the fastest it has ever gone. In fact, this is faster than even the usual bullet trains speeds of 320 km/h, though the world record stands at 603 Km/h. The test was conducted in a tube depressurised down to an equivalent air pressure found 200,000 feet above sea level
