Jet fighter planes are launched from aircraft carriers with the aid of their own engines and a catapult. If in the process of being launched from rest, the thrust of a jet's engines is 2.10 105 N and after moving through a distance of 90 m the plane lifts off with a kinetic energy of 5.20 107 J, what is the work done (in J) on the jet by the catapult
