    Work done = force * distance

    Since this is about raising an object then it is potential work done

    Workdone = mass * gravitational * height

    W=mgh

    m is 8kg

    W is 490J

    h=?

    g is 9.8m/s2

    Making h subject of formulas

    h=W/mg

    h = 490 / (8*9.8)

    h = 6.25m
