Question 35
Easy

A crane at a port is used to lift a shipping container.

A shipping container is suspended by a crane. It is lifted from a flat quay (point A) up onto a shipping vessel (point B). A vertical dashed line indicates the change in vertical height, h, between the quay level and the vessel deck level.

The mass of the container is 1500 kg.

The container gains 45 000 J45\ 000\text{ J}45 000 J of gravitational potential energy as it is hoisted from A to B.

State the equation relating change in gravitational potential energy, mass, gravitational field strength, and change in vertical height.
