A heavy-duty courier drone has a total mass of 7.5 kg (including its cargo).
The drone ascends vertically to deliver a package to a high-rise balcony located at a height of 64 m above its launch point.
Calculate the increase in gravitational potential energy of the drone.
Use the equation:
gravitational potential energy=mass×gravitational field strength×height \text{gravitational potential energy} = \text{mass} \times \text{gravitational field strength} \times \text{height} gravitational potential energy=mass×gravitational field strength×heightGravitational field strength, g=9.8 N/kgg = 9.8\text{ N/kg}g=9.8 N/kg.
