Potential Energy -- Kinetic Energy This graph shows different types of energy for a roller coaster car that starts at the top of a large hill and goes down to its lowest point at 6 s. According to the graph, what is the most likely relationship between height and potential energy? Your answer: They are directly related. They are inversely related. There is no relationship between the two. There is not enough information for a conclusion.
The figure shows a plot of potential energy U versus position x of a 0.270 kg particle that can travel only along an x axis under the Influence of a conservative force. The graph has these values: UA9.00 ). Uc 20.0 J and Ug 24.0J. The particle is released at the point where Uforms a "potential hill" of "height" Ua 12.0J. with kinetic energy 7.50 J.What is the speed of the particle at la) -3.50m and (b)x - 6.50 m? What is the position of the turning paint on (c) the right side and (d) the left side?
