Boeing 767-400ER model airplane has two engines. Each engine can have a maximum thrust (mechanical force) output of 270 kN. When the plane is cruising at 739.64 km/h, the pilot decides to increase the speed to the typical 850.0 km/h. If drag on the plane is on average 28657 N, and the engines are engaged at 35.84% of their maximum thrust output, and the plane weighs 156892 kg, how long does it take to reach the new cruising speed? Include...
