An airplane of mass 1.6 x 10^4 kg is moving at 58 m/s. The pilot then revs up the engine so that the forward thrust by the air around the propeller becomes 7.0 x 10^4 N. If the force exerted by air resistance on the body of the airplane has a magnitude of 6.0 x 10^4 N, find the speed of the airplane after it has traveled 500 m. Assume that the airplane is in level flight throughout this motion.
