Question part Points Submissions 1 2 3 4 0/1 0/1 0/1 0/1 0/5 0/5 0/5 0/5 A single conservative force = (4.0x - 12) N where x is in meters, acts on a particle moving along an x axis. The potential energy U associated with this force is assigned a value of 22 J at x = 0. (a) Write an expression for U as a function of x, with U in joules and x in meters. (Use x as appropriate in your symbolic expression.) U(x) = 1 (b) What is the maximum positive potential energy?2 J(c) At what negative value of x is the potential energy equal to zero?3 m(d) At what positive value of x is the potential energy equal to zero
