A fighter jet accelerates from rest along the flight deck of an aircraft carrier. At take-off, the jet has a speed of 80 m/s80\text{ m/s}80 m/s. The mass of the jet is 12 000 kg12\,000\text{ kg}12000 kg.
Calculate the kinetic energy of the jet at take-off.
An electromagnetic catapult system provides a constant accelerating force on the jet over a distance of 160 m160\text{ m}160 m along the deck. Calculate the average resultant force exerted on the jet. Assume that all of the kinetic energy at take-off is due to the work done on the jet by the catapult system.
