    150 J.

    Explanation:

    Work-done: This can be defined as the product of force and distance moved along the direction of the force.

    The S. I unit of work is Joules (J).

    From the question,

    W = F*d ... Equation 1

    Where W = work done, F = force, d = distance.

    Given: F = 25 N, d = 6 m

    Substitute into equation 1

    W = 25*6

    W = 150 J.

    Hence the work done by Marissa = 150 J

    150J

    Explanation:

    The following data were obtained from the question:

    M (mass) = 12Kg

    F (force) = 25N

    d (distance) = 6m

    w (work) = ?

    Work is defined as the product of force and distance moved in in the direction of the force. It is measured in joules and can be represented mathematically as:

    work = force x distance

    w = F x d

    w = 25 x 6

    w = 150J

    Therefore, 150J of work is done
