Acutting tool several forces acting on it. one force is f=-axy^2 j , a force in the negative y-direction whose magnitude depends on the position of the tool. the constant is a= 2.85 . consider the displacement of the tool from the origin to the point x=2.40 , y=2.40 .. calculate the work done on the tool by f if this displacement is along the straight line y=x that connects these two points.. calculate the work done on the tool by f if the tool is first moved out along the x-axis to the point x=2.40, y=0 , and then moved parallel to the y-axis to x=2.40

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
