Acutting tool under microprocessor control has several forces acting on it. one force is , a force in the negative y-direction whose magnitude depends on the position of the tool. the constant is α = 2.50 n/m³. consider the displacement of the tool from the origin to the point x= 3.05 m , y= 3.05 m . calculate the work done on the tool by if this displacement is along the straight line y = x that connects these two points.
