    Answer:

    PE = 882 J

    Explanation:

    Through the International System we know that the gravity of the earth is 9.8 m/s², so…

    Data:

    • m = 45 kg
    • g = 9.8 m/s²
    • h = 2 m
    • PE = ?

    Formula:

    • \boxed{\bold{PE=m*g*h}}

    Replace and solve:

    • \boxed{\bold{PE=45\ kg*\ 9.8\frac{m}{s^{2}}*2\ m}}
    • \boxed{\boxed{\bold{PE=882\ J}}}

    The potential energy of the sled is 882 Joules.

    Greetings.
