    Answer:

    P.E = 980 Joules

    Explanation:

    Given the following data;

    Mass = 20 kg

    Height = 5m

    Acceleration due to gravity = 9.8 m/s²

    To find the potential energy stored in the block;

    Mathematically, potential energy is given by the formula;

    P.E = mgh

    Where,

    P.E represents potential energy measured in Joules.

    m represents the mass of an object.

    g represents acceleration due to gravity measured in meters per seconds square.

    h represents the height measured in meters.

    Substituting into the equation, we have;

    P.E = 20 * 9.8 * 5

    P.E = 980 Joules
