The MIG 21 can reach speeds up to Mach 2.2 or 2,350 km/hr (1,468 mph)
MIG21 is called the flying coffin
Both HAL Tejas as well as Mig21 are old rated aircrafts. HAL Tejas has been prepared by the Hindustan Aeronautical Limited for the best use of trainees and all. Mig21 in Indian Air Force has been grounded a long back ago. Both the planes don't match up with fourth generation.
Only 3 US MARINE aviators were confirmed to have aerial kills during the Vietnam War; all three airmen flew the F4 Phantom, with USAF, USN backseaters: 1. CPT Doyle D. Baker (one MIG17) 2. CPT Lawrence G. Richard (one MIG21) 3. MAJ Lee T. Lasseter (one MIG21)
Vietnam gave the "cold war" leaders the opportunity to perfect their "cold war" weapons...by actually using them in combat; e.g. the B52 & the MiG21 for example. SAMs and their accompanying radars as another example.
The USSR trained North Vietnamese MIG17 & MIG21 pilots in the Soviet Union, about two years per man. The USSR also gave MIG17 & MIG21 jets to the North Vietnamese Air Force. USSR supplied SAMs (Surface to Air Missiles) and AAA (Anti-Aircraft Artillery) to North Vietnam. USSR supplied PT76 Amphibious Light Tanks, and T54/T55 Medium tanks to the North Vietnamese Army (NVA). Communist China Trained North Vietnamese MIG19 pilots in Red China, and also supplied the North Vietnamese Air Force with MIG19 (J6 versions) jet fighters.
The future tense for speed is will speed.
Via proxy, the USSR & US got to test some weapons there. Not too many though, as Vietnam had already tested most of them: SAMs, T54/55 medium tanks, PT76 tanks, MiG17, MiG19, MiG21 jets, Sagger Wire Guided Missiles, etc.
there's four speed. There are constant speed, average speed, increasing speed, and decreasing speed. choose one of them
No instantaneous speed is not final speed.
Walking speed Bicycle speed Automobile speed Train speed Airplane speed Rocket speed
Perhaps coincidentally, the phrase "light speed" refers to a speed.It is a speed.
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
