Gravitational potential energy

In summary, a fully loaded Cessna-182 airplane experiences an engine failure while flying at an airspeed of 126 km/h and an altitude of 2540 m. It then glides at a constant speed of 126 km/h, with a drag force of 1300 N opposing its direction of flight. The rate at which it is losing gravitational potential energy is 47.3, using the equation g = 9.81 m/s^2.

Homework Statement


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 don't know how to get it

Related to Gravitational potential energy

What is gravitational potential energy?

Gravitational potential energy is a form of potential energy that is associated with the position of an object in a gravitational field. It is the energy an object possesses due to its position in a gravitational field and is a result of the gravitational force acting on the object.

How is gravitational potential energy calculated?

The gravitational potential energy of an object can be calculated using the formula U = mgh, where U is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

What factors affect the gravitational potential energy of an object?

The gravitational potential energy of an object is affected by its mass, the strength of the gravitational field, and the height of the object. The higher the mass and the height of the object, the greater its gravitational potential energy will be.

Can gravitational potential energy be converted to other forms of energy?

Yes, gravitational potential energy can be converted into other forms of energy, such as kinetic energy, when an object falls or moves in a gravitational field. This conversion is described by the law of conservation of energy.

What is the practical application of gravitational potential energy?

Gravitational potential energy has many practical applications, such as in hydropower plants where the potential energy of water stored in dams is converted into electrical energy. It is also used in roller coasters and other amusement park rides to provide thrilling experiences for riders.
