read the text about a person in motion. hayley performs stunts on movie sets. for one stunt, hayley started on the first story of a building. she ran up a staircase until she reached the third story. she dashed to a balcony, where she slid down a rope into an open window on the second story of another building. she landed safely on the floor inside the open window. when was the least gravitational potential energy stored between hayley and earth? assume that hayleys mass did not change. when she was at the bottom of the staircase when she was standing on the balcony when she was on the floor inside the window

read the text about a person in motion. hayley performs stunts on movie sets. for one stunt, hayley started on the first story of a building. she ran up a staircase until she reached the third story. she dashed to a balcony, where she slid down a rope into an open window on the second story of another building. she landed safely on the floor inside the open window. when was the least gravitational potential energy stored between hayley and earth? assume that hayleys mass did not change. when she was at the bottom of the staircase when she was standing on the balcony when she was on the floor inside the window

Answer

Explanation:

Step1: Recall gravitational - 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 the height above the ground. Given that $m$ and $g$ are constant, $U$ depends only on $h$.

Step2: Analyze height at different positions

She starts on the first - story, goes to the third - story, then to the second - story. The floor inside the open window is the lowest position among the given options. At this position, $h$ is the smallest. Since $U = mgh$ and $m$ and $g$ are constant, when $h$ is the smallest, $U$ is the smallest.

Answer:

when she was on the floor inside the window
