The potential energy, VVV Joules, of a mechanical system depends on a configuration parameter xxx according to the model:
V=13x3+52x2−24x+10V = \frac{1}{3}x^3 + \frac{5}{2}x^2 - 24x + 10V=31x3+25x2−24x+10
Use calculus to find the values of xxx for which the system's potential energy is stationary.
By using the second derivative, determine the nature of each of these stationary points.
