    The answer to your question is Pe = 2452.5 J

    Explanation:

    Data

    mass = 50 kg

    height = 5 m

    gravity = 9.81 m/s²

    Process

    The energy of this process is Potential energy which is proportional to the mass of the body, the gravity and the height of the body.

    Pe = mgh

    Substitution

    Pe = (50) (5) (9.81)

    Simplification

    Pe = 2452.5 J
