    Mass of the object = 1000 kg

    height = 146

    meter acceleration due to gravity = 9.8 m/s^2

    but for easy calculation we will take acceleration due to gravity as

    = 10 m/s^2

    So for this,

    W = 1000 x 10 x 146

    W = 1460000 J

    W = 1.46 x 10^6 J

    answer is = 1.46 x 10^6J
