How long would it take a 1.5 x 10^5 kilogram airplane with engines that produce 100 megawatts of power to reach a speed of 250 m/s at an altitude of 12 kilometers is air resistance were negligible? If it actually takes 900 seconds, what is the power? Given this power what is the average force of air resistance if the airplane takes 1200 seconds? (Hint: you must find the distance the plane travels in 1200 seconds assuming constant acceleration.)
