    Work done by george = 35.28J

    Step-by-step explanation:

    We are given;

    Mass; m = 2 kg

    Height; h = 1.8 m

    Now, we want to find how much work does George do on a 2-kg package at the height of 1.8m.

    This is a potential energy problem.

    The formula for work done is therefore;

    W = mgh

    Where;

    m is mass

    g is acceleration due to gravity which has a constant value of 9.8 m/s²

    h is height

    Thus, plugging in relevant values;

    W = 2 x 9.8 x 1.8

    W = 35.28 J
