The figure shows a plot of potential energy U versus position x ofa 2.7 kg particle that can travel only along an x axis under theinfluence of a conservative force. The graph has these values: UA =9.0 J, UB = 12.0 J, UC = 19.0 J, and UD = 22.0 J. The particle isreleased at the point where U forms a "potential hill" of "height"UB, with kinetic energy 4.0 J. What is the speed of the particle atx = 3.5 m?
Here's the graph :http://nplq1.phyast.pitt.edu/res/sc/gblanpied/courses/usclib/hrw8/hrwpictures/hrw8c8f051.jpg
