1.	A jet airplane is travelling at 200 ms^(-1) . The engine of the plane takes in 250 m^(3) of air of mass 32 kg each second . The air is used to burn 3 kg of fuel each second . The energy is used to compress the products of combustion to eject them at the rear of the plane at 500 ms^(-1) relative to the plane . Find the power of the jet plane in H.P.(1 H.P = 746 W). [Hint : Resultant thrust = forward thrust - backward thrust and power = force xx velocity ]
