    The amount of work done on the weights would be approximately 15.0 Kg of work

    1200Nm

    Explanation:

    Work is said to be done if a force applied to an object causes the object to move through a distance. Mathematically,

    Work done = Force * Distance

    Given distance = 2m

    Mass of the body = 60kg

    The weight W of the bodies = mass * acceleration due to gravity

    W = 60*10 = 600N

    Work done = 600*2

    Work done = 1200Nm

    1200Nm of work is done on the weights
