Figure 8-47 shows a plot of potential energy U versus position x ofa 0.240 kg particle that can travel only along an x axis under theinfluence of a conservative force. The graph has these values: UA =9 J, UC = 20 J and UD = 24 J. The particle is released at the pointwhere U forms a âpotential hillâ of âheightâ UB = 12 J, withkinetic energy 6.50 J. What is the speed of the particle at (a)x =3.5 m and (b)x = 6.5 m? What is the position of the turning pointon (c) the right side and (d) the left side?
