The work done against gravity is 34563738.59 Joule.

Scientifically work done components will be given as, W = F × d. In this situation, the force exerted on the block is constant, but the course of force and the path of displacement stimulated by way of this pressure are exceptional. Force F reacts at a perspective θ to the displacement d.To express this concept mathematically, the work W is the same as the pressure f instances of the distance d or W = fd. If the pressure is being exerted at an attitude θ to the displacement, the work finished is W = FD cos θ.

If pressure is implemented on a system and the system studies a displacement then the work is said to be done at the gadget. If a gadget applies a force on something else and reasons displacement then the painting is said to be finished through the device.

Calculation:-

work done = force × displacement

= ma × 2500 ft

= 45359.237 kg × 762 meter

= 34563738.59 Joule.
