A crane lifts a crate of mass 600 kg to the top of a building.
The crate gains 210 000 J210\,000\text{ J}210000 J of gravitational potential energy.
The gravitational field strength is 10 N/kg.
Use the equation:
Potential energy=Mass×Height×Gravitational field strength \text{Potential energy} = \text{Mass} \times \text{Height} \times \text{Gravitational field strength} Potential energy=Mass×Height×Gravitational field strengthCalculate the height that the crate is lifted.
