= 6.98 CALC An object has several forces acting on it. One of these forces is F axy, a force in the x-direction whose magni- tude depends on the position of the object, with a = 2.50 N/m. Calculate the work done on the object by this force for the following displacements of the object: (a) The object starts at the point x = 0, y = 3.00 m and moves parallel to the x-axis to the point x = 2.00 m, y 3.00 m. (b) The object starts at the point 2.00 m, y = 0 and moves in the y-direction to the point x = 2.00 m, y = 3.00 m. (c) The object starts at the origin and moves on the line y 1.5x to the point x = 2.00 m, y = 3.00 m. x = = =
