Figure 1 shows a drone lifting a cargo package vertically up a steep cliffside.

A schematic diagram of a drone lifting a cargo package vertically up a cliffside, showing height difference delta h and package mass m.

The cargo package has a mass of 1.80 kg.

The package gains 291.06 J of gravitational potential energy as it is lifted from the ground to the ledge.

Calculate the increase in height, Δh\Delta hΔh, of the package.

Gravitational field strength, g=9.8 N/kgg = 9.8 \text{ N/kg}g=9.8 N/kg

Use the equation:

ΔEp=m×g×Δh \Delta E_p = m \times g \times \Delta h ΔEp​=m×g×Δh
