Consider a jet on the deck of an aircraft carrier. In order to take off, a catapult is attached to the jet and it is flung off t
he deck. An F-18 has a gross weight of approximately 17,000 kg and must reach speeds of about 270 km/hr by the end of the 150 m deck. The catapults on aircraft carriers must be able to launch a variety of aircraft that have different masses and minimum air speeds for flight! How would you ensure that you provide enough energy to the aircraft to get it safely off the deck of the aircraft carrier?
The burning of the sun is not chemical combustion. It is nuclear fusion. This combustion releases energy which we experience as the heat and light given off by the flame.
