(a) How long would it take a 1.50 x 10^5 kg airplane with engines that produce a maximum of 100 MW of power to reach a speed of 200 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 of air resistance if the airplane takes 1200 s? (Hint: You must find the distance the plane travels in 1200 s assuming constant acceleration.)
