Answer:The objects in order from least to greatest potential energy:
3<1<4<2
Explanation:
1. Potential energy of a 15-kilogram stone found at a height of 3 meters:
[tex]mgh=15 kg\times 9.8 m/s^2\times 3 m=441 J[/tex]
2. Potential energy 10 kilograms of water stored at a height of 9 meters:
[tex]mgh=10 kg\times 9.8 m/s^2\times 9 m=882 J[/tex]
3. Potential energy 1-kilogram ball located 20 meters in the air:
[tex]mgh=1 kg\times 9.8 m/s^2\times 20 m=196 J[/tex]
4. Potential energy box of books weighing 25 kilograms placed on a shelf 2 meters high:
[tex]mgh=25 kg\times 9.8 m/s^2\times 2 m=490 J[/tex]
The objects in order from least to greatest potential energy:
3<1<4<2
