The table shows the potential energy and kinetic energy of a skier at two different positions on a hill.
Position and Energy
Position (above ground) Kinetic Energy Potential Energy
100 meters 0 units 50,000 units
60 meters ? 30,000 units
What is the kinetic energy of the skier at a height of 60 meters above ground?
Group of answer choices
20,000 units, because total energy remains unchanged
80,000 units, because total energy remains unchanged
20,000 units, because total energy of the skier decreases
80,000 units, because total energy of the skier decreases
