The potential energy of an object is determined by its height relative to a reference point (usually the lowest point in the system). In the case of a U-shaped ramp, the point where the person has the greatest potential energy would be at the highest point of the ramp.
Therefore, the correct answer is:
**C. At the top of the ramp before they begin moving down into the ramp.**
At this point, the person has the maximum height and hence the greatest potential energy.
Therefore, the correct answer is:
**C. At the top of the ramp before they begin moving down into the ramp.**
At this point, the person has the maximum height and hence the greatest potential energy.
