005 (part 1 of 2) 10.0 points A potential energy function is given by 3 U = Ax +Bx-Cx+D. For positive parameters A, B, C, D this po- tential has two equilibrium positions, one sta- ble and one unstable. Find the stable equilibrium position for A 1.25 J/m, B = 1.85 J/m, C = 1.7 J/m, and D = 0.4 J . Answer in units of m. 006 (part 2 of 2) 10.0 points What is the unstable equilibrium position? Answer in units of m.
