A particle A with mass m attached to one end of a spring of constant k and natural length I,. The other
end of the spring is fixed at a point F in the vertical direction (O y) at a distance h from the origin O. The
particle moves without friction on a support belonging to the horizontal direction (Ox) (see figure below).
If we assume that x represents the coordinate of the particle in the (Ox) direction:
a) Determine the differential work dW of the conservative forces applied to the particle.
b) Deduce the first derivative d of the potential energy U of the particle as function of h, x and lg-
c) Find the possible equilibrium positions.
