Question
An airplane of mas 1.50×104kg is in level flight initially moving at 60.0m/s the resistive force exerted by air on the airplane has a ,magnitude o f4.0×104N By Newton's third law, iof the engines exert a force on the exhaust gases to expel them out of the back of the engine, the exhaust gases exerts a force on the engines called thrust, and the value of the thrust in this situation is 7.50×104N Is the work done by the exhaust gases on the airplane during some time interval equal to the change in the airplane's kinetic energy? Explain.
