Calculate the work done if a 60 kg block of ice is pulled across a smooth surface using a chain 25o from the horizontal that pulls with a force of 110 N for 120 meters.

Wnet = Σ F d cos θ How would I use this equation to get the same result for net work in a problem where the work done by each force is added arithmetically?
