An object is subjected to a friction force with magnitude 4.26 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? (a) the purple path O to A followed by a return purple path to O J (b) the purple path O to C followed by a return blue path to O J (c) the blue path O to C followed by a return blue path to O J (d) Each of your three answers should be nonzero. What is the significance of this observation? The force of friction is a nonconservative force. The force of friction is a conservative force.
