Suppose a 1.55 × 10-kg airplane has engines that produce 85 mw of power. 33%
part (a) how many seconds would it take the airplane to reach a speed of 275 ms and an altitude of 10.5 km, if air resistance were negligible? 33%
part (b) how much power did the plane use, in megawatts, if this process actually took 825 s? -* 33%
part (c) using the power consumption from part (b), what would be the magnitude of the average force, in newtons, of the air resistance if the airplane took 1175 s and traveled in a straight line at a constant acceleration to the specified altitude?
