The potential energy function of a point mass is given by the expression: U(x) = 2x^2 - 8x, where x is the coordinate of the body and U is measured in Joules. Only conservative forces are acting. Find the kinetic energy of the body (in J) at the point of stable equilibrium if the mechanical energy of the body is 20 J.
