a) How long (in s) would it take a 2.00 ✕ 105 kg airplane with engines that produce of 100 MW of power to reach a speed of 250 m/s and an altitude of 12.0 km if air resistance were negligible?
(b) If it actually takes 850 s, what is the power applied, in megawatts?
(c) Given this power, what is the average force (in kN) of air resistance if the airplane takes 1200 s? (Hint: You must find the distance the plane travels in 1200 s assuming constant acceleration.)

The Boeing 747 has a cruising altitude of 45,000 feet and
cruising speed of 275 m/s. At this elevation, the temperature and
pressure according to the US Standard Atmosphere (air properties as
a function of altitude) are 220K and 1.8x104 Pa, respectively. The
engines are steady state devices that can be modeled using the 1st
Law of Thermodynamics with air (ideal gas) as the working fluid
undergoing several processes.
