An object is subjected to a friction force with magnitude 3.21 N, which acts against the object's velocity. What is the work (in J) needed to move the object at constant speed for the following routes? у (m) B (5.00, 5.00) x (m) A (a) the purple path O to A followed by a return purple path to O (b) the purple path O to C followed by a return blue path to O (c) the blue path O to C followed by a return blue path to O (d) Each of your three answers should be nonzero. What is the significance of this observation? The force of friction is a conservative force. The force of friction is a nonconservative force.
