"Work Done by 2-D Force"
What work is done by a force = ((1 N/m)x) + (4 N), with x in meters, that moves a particle from a position 1 = (2 m) + (3 m) to a position 2 = - (4 m) - (3 m)?
I figured all I would have to do is find the displacement of the x and y coordinates after the force had acted on them and then multiply the displacement vectors by their corresponding x and y force vectors, then use some trig to get the total work done. The answer I came up with was 35J, which of course was wrong. What am I missing? any help would be appreciated.
