The figure shows a plot of potential energy U versus position x of a 0.250 kg particle that can travel only along an x axis under the influence of a conservative force. The graph has these values: UA-9.00 J. Uc-20.0 J and Up-24.0 J. The particle is released at the point where U forms a "potential hill" of "height" UB-12.0J, with kinetic energy 7.50 J. What is the speed of the particle at (a)x -3.50 m and (b)x -6.50 m? What is the position of the turning point on (c) the right side and (d) the left side?
