A64.0-kg hiker is descending a mountain that has a peak altitude of 2350 m above sea level. the hiker has a device that measures her potential energy, and when she is at the peak of the mountain she decides to "zero" it (that is, she sets the zero point of potential energy to be the mountaintop). what does her potential energy device read sometime later on her descent when she is 1960 m above sea level
