A 0.20-kg particle moves along the x axis under the influence of a conservative force. The potential energy is given byU(x) = (8.0 J/m2)x2 + (2.0 J/m4)x4,where x is in coordinate of the particle. If the particle has a speed of 5.0 m/s when it is at x = 1.0 m, its speed when it is at the origin is:a) 0 m/sb) 2.5 m/sc) 5.7 m/sd) 7.9 m/se) 11 m/s
