A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (3.01 m, 4.12 m) while a constant force acts on it. The force has magnitude 1.54 N and is directed at a counterclockwise angle of 100° from the positive direction of the x axis. How much work is done by the force on the coin during the displacement?
