    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:

    • \boxed{\bold{PE=m*g*h}}

    Replace and solve:

    • \boxed{\bold{PE=12\ kg*9.8\frac{m}{s^{2}}*2\ m}}
    • \boxed{\boxed{\bold{PE=23.8\ J}}}

    The potencial energy is 23.8 Joules.

    Greetings.
