Total 0/4 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
