Unformatted text preview: 89 2. Friction Force: Motion on a Horizontal Plane Now consider the same diagram for a book on a horizontal table where there is a frictional force of 5 N on the book. B is located 2 m north and 1.5 m east of A. The book is at rest at the start and end of its motion. (a) What is the net work done on the book for each of the three paths? (b) Determine the work done by the force of friction for Path 1. (c) Determine the work done by the force of friction for Path 2. (d) Determine the work done by the force of friction for the diagonal line, Path 3 . (e) Are your answers the same or different for the three paths? (f) Does the work of friction equal the net work? Why or why not? Which of these forces is "Conservative" and which is "NonConservative"? Why?...
