A particle with mass 2.55 kg is moving in one dimension subject to a potential energy function that is a 4th-order polynomial. There are equilibrium points at x = -2 m, x = 1 m, and x = 3 m. The potential energy is zero at the origin. When the particle is located at x = -2 m, it has a potential energy of 22.3 J and is moving with a speed of 5.4 m/s. What is the speed of the particle when it is located at x = 2 m?
