Determine the work done by the force F = (4.80x1 +8.00y) N/m acting on an object as it moves in the following manners. (a) along the x axis from x; = 0 to xf = 4.91 m 23.568 Given a variable force F and the path dr over which this force acts, how can we determine the work done by the force? J (b) along the y axis from y; = 0 to yf = 3.50 m 28.0 Given a variable force F and the path dr over which this force acts, how can we determine the work done by the force? J (c) from the position (xi, yi) = (0, 0) to the position (X, Y) = (4.91 m, 3.50 m) 51.568 Given the work done by a variable force F acting over two path segments dra and dry, how can we determine the total work done?
