In order for planes to take off from an aircraft carrier deck, they need an initial speed boost. this initial speed is provided by the aircraft carrier in the form of a catapult system (using either steam or electromagnetic force). we want to take off an f-22 from an aircraft carrier. the f-22 has a mass of 21430 kg and the aircraft catapult pushes the airplane across its 98 m long flight deck with a constant force of 415000 n. assume the flight deck is level. a) what is the velocity of the f-22 as it leaves the flight deck? b) if the aircraft carrier flight deck is 21 m above the ocean surface, then how much time does the f-22 have to begin flying once it leaves the flight deck? c) how far away from the aircraft carrier does the f-22 travel in the time calculated in part b) (assume the aircraft carrier remains stationary and the plane does not start flying)?
