A ball slides from the top of a hill (point A) to the bottom (point B) along a curved path. The vertical height of point A above the base is H. Which of the following statements is correct?

Options

The length of the curved path from A to B is unknown, so the work done by gravity cannot be determined.

The resistance force along the path is unknown, so the work done by gravity cannot be determined.

The work done by gravity from A to B is mg(H+h).

The work done by gravity from A to B is mgH.
