Understanding the potential energy changes along the path can provide valuable insights into the energy state of the system. Suppose a one-dimensional system (m = 400 g) is being acted upon by a conservative force F_x, with the potential energy set to zero at a reference point x = x₀. Calculate the system's potential energy at various points along the path: (i) x = x₀ + 2.0 m, (ii) x = x₀ + 4.0 m, (iii) x = x₀ + 6.0 m, and (iv) x = x₀ + 8.0 m, where x₀ = 0 m.
