A ball is released from rest at the left of the metal track shown. Assume it has only enough friction to roll, but not to lessen its speed. Rank PEs from greatest to least at each point.Rank from greatest to least. To rank items as equivalent, overlap them. The image is a simple diagram with a wavy line connecting four labeled points: A, B, C, and D. Explanation:- Point A is on the far left, marked with a small loop.- Moving from A to B, the line dips slightly and flattens out.- From B to C, the line dips further before rising slightly.- Finally, the line moves from C to D, which includes a gradual rise and fall.- There is a horizontal dashed line running parallel to the path from A to D, indicating a baseline or reference level. This type of diagram could represent a variety of concepts, such as a journey with elevation changes, or a conceptual model illustrating phases or states connected sequentially.

Let the mass of ball = m Let acceleration due to gravity = g The potential energy of an object is given by the formula : Potential energy = mass×g×height Thus, the position where ball is at maximum height has maximum potential energy .The position where the ball has minimum height , is the position corresponding to least potential energy Therefore, maximum potential energy possesed by the ball is at point A , and the least potential energy possesed by the ball is at point C . The potential energy of the ball at B and D are equal because the height of the ball at thesetwo points are equal. Therefore, Potential energy at A > Potential eenergy at B = Potential energy at D > Potential energy at CA > B=D >C
