A fully loaded Cessna-182 airplane of mass 1250 kg has an engine failure when flying with an airspeed of 126 km/h at an altitude of 2540 m on a calm day. It then glides at a constant glide angle (which is the direction of flight below the horizontal) towards a safe landing at this constant speed of 126 km/h experiencing a drag force of 1300 N that opposes the direction in which the plane is moving.
Please use: g = 9.81 m s-2
2. Homework Equations
Find the rate with which the loaded plane is losing gravitational potential energy.
the answer is 47.3 but i dont know how to get it
