A force acts on a particle which moves from the origin to point C. The particle can travel along three different paths: OBC, OC, and OAC. The following is the work done by the force for each path: WOBC = 50 J, WOAC = 125 J, WOC = 66.7 J. Is the force conservative or non-conservative? b. Three conservative forces and two nonconservative force act on a system. What is the maximum number of potential energy terms could there be in describing the system?
