Work in an Inertial Reference Frame

A constant force $extbf{F} = (3 extbf{i} + 4 extbf{j}) \text{ N}$ acts on a 2 kg object. In reference frame S’, the object undergoes a displacement of 3 m in the positive x-direction. A second reference frame, S, moves at 5 m/s in the positive x-direction relative to S’. What is the work done by the force during this displacement?
