A coin slides over a friction-less plane and across an x-y coordinate system from the origin to a point with x-y coordinates (3.9 m, 8.4 m) at the same time a constant force acts on it. The force consists of a magnitude 3.4 N and is directed at a counterclockwise angle of 124° from the positive direction of the x axis. Determine how much work is done by the force on the coin throughout the displacement?
