although the roller coaster car at position 3 is decreasing in potential energy relative to position 1, it has the same potential energy as it has at
choices: position 2 or position 4
a roller coaster ride

Explanation:

Step1: Recall potential energy concept

Potential energy of an object in a gravitational - field depends on its height.

Step2: Compare heights

The height of the roller - coaster car at Position 3 is the same as the height of the car at Position 2. Since potential energy \(PE = mgh\) (where \(m\) is mass, \(g\) is gravitational acceleration, and \(h\) is height), when \(m\) and \(g\) are constant, equal height means equal potential energy.

Answer:

Position 2
