7.83 ... CALC A cutting tool under microprocessor control has several forces acting on it. One force is F = -axy'j, a force in the negative y-direction whose magnitude depends on the posi- tion of the tool. The constant is a = 2.50 N/m*. Consider the displacement of the tool from the origin to the point x = 3.00 m, y = 3.00 m. (a) Calculate the work done on the tool by F if this displacement is. along the straight line y = x that connects these two points. (b) Calculate the work done on the tool by F if the tool is first moved out along the x-axis to the point x = 3.00 m, y = 0 and then moved parallel to the y-axis to the point x = 3.00 m, y = 3.00 m. (c) Compare the work done by É along these two paths, Is F conservative or nonconservative? Explain. %3D

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
