Answer:
PE = 23.8 J
Explanation:
It's known through the International System that the gravity of the earth is 9.8 m/s², so we have as...
Data:
- m = 12 kg
- g = 9.8 m/s²
- h = 2 m
- PE = ?
Use formula:
- [tex]\boxed{\bold{PE=m*g*h}}[/tex]
Replace and solve:
- [tex]\boxed{\bold{PE=12\ kg*9.8\frac{m}{s^{2}}*2\ m}}[/tex]
- [tex]\boxed{\boxed{\bold{PE=23.8\ J}}}[/tex]
The potencial energy is 23.8 Joules.
Greetings.
