Explanation:

Step1: Recall potential energy formula

The gravitational - potential energy formula is $U = mgh$, where $m$ is mass, $g$ is the acceleration due to gravity, and $h$ is height. Assuming the mass of the roller - coaster and $g$ are constant, potential energy depends only on height.

Step2: Identify the highest point for first question

In the first question, we need to find the point with the most potential energy. By comparing the heights of points A (30m), B (12m), C (25m), and D (12m), point A has the highest height. So the roller - coaster has the most potential energy at point A.

Step3: Identify the second - highest point for second question

In the second question, we need to find the point with the second - most potential energy. After point A, point C has the second - highest height (25m).

Answer:

1. point A
2. point C
