The Figure here shows a plot of potential energy U versus position x of a 0.883 kg particle that can only travel along an x axis ( Non conservative forces are not involved. Three values are UA= 15 J, UB= 35 J, UC= 45 J. An object is released at 4.5 m with 10.0 J of kinetic energy. Use 3 sig figs in your answers.
a) What force acts on the object with it just past 4.0 m heading left?
b) What is the turning point in the left side of the graph?
c) What is the objects speed at 3.5 meters
