Question

What is the potential energy of the skier at a height of 60 meters above the ground?

1 - 30,000 units, because total energy decreases
2- 70,000 units, because total energy decreases
3 - 30,000 units, because total energy remains unchanged
4- 70,000 units, because total energy remains unchanged

Answer 1

well we can elminate 1 and 2 because of the law of conservation of energy

Answer 2

yea i thought that too

Answer 3
