Find net force from acceleration

A rescue winch test of mass \(10\,\text{kg}\) accelerates at \(2.75\,\text{m s}^{-2}\). Calculate the net force. Identify the force, momentum, or energy relationship before entering the result. Enter the numerical result and choose the interpretation that matches the mechanics meaning.
