1. An aircraft with a weight of 9278 N accelerates from 0 to 88 m/s in 11.1 seconds, at which time the aircraft launches. What is the kinetic energy of the aircraft when the aircraft launches?
2. An aircraft with a mass 216 kg is accelerated at 9.2 m/s2 for 5 seconds, at which time the aircraft launches. Assume the acceleration is constant. What is the force required to launch the aircraft?
