He table shows the potential energy and kinetic energy of a skier at two different positions on a hill. position and energyposition (above ground) kinetic energy potential energy100 meters 0 units 50,000 units30 meters 35,000 units ? what is the potential energy of the skier at a height of 30 meters above the ground? 85,000 units, because total energy increases15,000 units, because total energy is 50,000 units15,000 units, because total energy is 85,000 units85,000 units, because total energy remains unchanged

15,000 units, because total energy is 50,000 units

Explanation:

According to law of conservation of energy, energy remains conserved. It only transforms from one form to another.

The total energy here is the sum of kinetic and potential energy.

At 100 meters, total energy = Kinetic energy + potential energy = 0 units + 50000 units = 50000 units

At 30 meters, total energy = Kinetic energy + potential energy = 35000 units + x units = 50000 units

x units = 15000 units

Thus if the kinetic energy has increased from 0 to 35000 units, the potential energy must decrease from 50000 to 35000 units to keep the energy conserved.

the answer is either b or c
