    Answer:

    • the gravitational force of the counterweight is 19.6 N
    • the work done is 9.8 J

    Explanation:

    Question 1:

    Given;

    a counterweight of mass, m = 2-kg

    distance moved by this weight, d = 0.5 meters

    the gravitational force of the counterweight is calculated as;

    F = mg

    where;

    F is gravitational force

    m is the mass

    g is acceleration due to gravity

    F = 2 x 9.8 = 19.6 N

    Thus, the gravitational force of the counterweight is 19.6 N

    Question 2:

    Given;

    a counterweight of mass, m = 2-kg

    height moved by this weight, h = 0.5 meters

    the work done is calculated as;

    Work done = Force x distance moved by this weight

    Work done = 19.6 x 0.5 = 9.8 J

    Thus, the work done is 9.8 J
