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 717.25 km/h, the pilot decides to increase the speed to the typical 850.0 km/h. If drag on the plane is on average 26188 N, and the engines are engaged at 55.42 % of their maximum thrust output, and the plane weighs 149375 kg, how long does it take to reach the new cruising speed?

An airplane has a mass of 48,000 kg, a wing area of 300 m2, a maximum lift coefficient of 3.2, and a cruising drag coefficient of 0.03 at an altitude of 12,000 m. Determine(a) the takeoff speed at sea level, assuming it is 20 percent over the stall speed, and (b) the thrust that the engines must deliver for a cruising speed of 900 km/h.
