Question:

A 30-seat turboprop airliner whose mass is 14,000 kg takes off from an airport and eventually achieves its cruising speed of 620 km/h at an altitude of 10,000 m. For g= 9.78 m/s2, determine the change in kinetic energy and the change in gravitational potential energy of the airliner, each in kJ
