Question

(a) How long would it take a 1.00 ? 105 kg airplane with engines that produce a maximum 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?
__________S
(b) If it actually takes 925 s, what is the power applied, in megawatts?
___________ MW
(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.)
______________ kN
