1. The problem statement, all variables and given/known data A coin slides over a frictionless plane and across an xy coordinate system from the origin to a point with xy coordinates (1.5 m, 4.5 m) while a constant force acts on it. The force has magnitude 7.8 N and is directed at a counterclockwise angle of 105° from the positive direction of the x axis. How much work is done by the force on the coin during the displacement? 2. Relevant equations I used the equation Fxdx + Fydy = W 3. The attempt at a solution I used cosine and sine to find the x and y components of the Force. And the x and y coordinates for the displacement were already given. I figured everything would work when I plug those in, but I had no luck. Any idea what I did wrong?
