The result is surprising as the catapult actually do much more work than the engine itself (almost 21 times more)!

thank you for the reply!

Q.2 engine has done 23000x87 of work , total work has to be 4.5 x10^7 J as this is the lift off energy(NOT SURE)? so work done by catapult should be 4.5x10^7-23000x87=42999000

Q2 AND Q5 are the questions I struck in at the minute. For Q 2 , I wonder i could simply use change of kinetic energy=Work done, does the catapult gain the same amount of energy as the Jet fighter?? For Q.5, i have no idea where to start, could someone at least give me some kind of direction...
