Force acceleration work chain

A \(3\,\text{kg}\) object in a medical linac calibration accelerates at \(1.8\,\text{m s}^{-2}\) over \(6\,\text{m}\). Calculate the work done by the net force. Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
